front-end if the dpt(4) module is built along with a kernel that
includes eisa(4) or when compiling it stand-alone (logic based on
the corresponding ISA logic in sys/modules/sound/sound/Makefile).

H A DMakefile211157 Tue Aug 10 23:08:25 MDT 2010 will Allow carp(4) to be loaded as a kernel module. Follow precedent set by
bridge(4), lagg(4) etc. and make use of function pointers and
pf_proto_register() to hook carp into the network stack.

Currently, because of the uncertainty about whether the unload path is free
of race condition panics, unloads are disallowed by default. Compiling with
CARPMOD_CAN_UNLOAD in CFLAGS removes this anti foot shooting measure.

This commit requires IP6PROTOSPACER, introduced in r211115.

One of the features that prevented us from fixing some of the TTY
consumers to work once again, was an interface that allowed consumers to
do the following:

- `Sniff' incoming data, which is used by the snp(4) driver.

- Take direct control of the input and output paths of a TTY, which is
used by ng_tty(4), ppp(4), sl(4), etc.

There's no practical advantage in committing a hooks layer without
having any consumers. In P4 there is a preliminary port of snp(4) and
thompsa@ is busy porting ng_tty(4) to this interface. I already want to
have it in the tree, because this may stimulate others to work on the

r248925:
Support for Chelsio's 40G Terminator 5 (aka T5) ASIC.
...

r249368:
Set and display the IP fragment bit correctly when dealing with
the filter mode.

r249370:
cxgbe(4): Ensure that the MOD_LOAD handler runs before either t4nex or
t5nex attach to their devices.

r249376:
- Explain clearly why a different firmware is being installed (if/when
it is being installed). Improve other error messages while here.

- Select special FPGA specific configuration profile when appropriate.

r249382:
There is no need for elaborate queries and error checking when trying to
set FW4MSG_ENCAP.

r249383:
Get rid of a couple of stray \n's.

r249385:
cxgbe/tom: Slight simplification of code that calculates options2.

r249391:
Auto-reduce the holdoff timers that are greater than the maximum value
allowed by the hardware.

r249392:
Cosmetic change (s/wrwc/wcwr/;s/WRWC/WCWR/).

r249393:
Add pciids of the T5 based cards. The ones that I haven't tested with
cxgbe(4) are disabled for now. This will change.

r249627:
cxgbe/tom: Update the CLIP table on the chip when there are changes
to the list of IPv6 addresses on the system. The table is used for
TOE+IPv6 only.

r249629:
cxgbe(4): Refuse to install T5 firmwares on a T4 card (and vice versa).

r250090:
cxgbe(4): Some updates to shared code.

r250092:
- Provide accurate ifmedia information so that 40G ports/transceivers are
displayed properly in ifconfig, etc.

- Use the same number of tx and rx queues for a 40G port as for a 10G port.

r250093:
Attach to the T580 (2 x 40G) card.

r250117:
Fix DDP breakage introduced in r248925. Bitwise OR has higher
precedence than ternary conditional.

r250218:
cxgbe/tom: Do not use M_PROTO1 to mark rx zero-copy mbufs as special.
All the M_PROTOn flags are clobbered when an mbuf is appended to the
socket buffer.

r250221:
cxgbe: Switch to a better way to install firmware.

r250614:
Deal correctly with 40G ports that don't have any transceiver plugged
in. Do not claim that they have unknown tranceivers.

r251213:
cxgbe(4): Some more debug sysctls. These work on both T4 and T5 based
cards.

r251317:
cxgbe(4): t4fw_cfg must be explicitly loaded if the driver is being
loaded via loader.conf.

r251358:
cxgbe(4): Provide accurate hit count for filters on T5 cards. The
location within the TCB and the size have both changed.

r251434:
cxgbe(4): Never install a firmware if hw.cxgbe.fw_install is 0.

r251518:
cxgbe/tom: Fix bad signed/unsigned mixup in the stid allocator. This
fixes a panic when allocating a mixture of IPv6 and IPv4 stids.

r251638:
cxgbe/tom: Allow caller to select the queue (control or data) used to
send the CPL_SET_TCB_FIELD request in t4_set_tcb_field().

r252312:
Update T5 register ranges. This is so that regdump skips over registers
with read side-effects.

r252469:
Add a sysctl to get the number of filters available.

sysctl dev.t4nex.<N>.nfilters
sysctl dev.t5nex.<N>.nfilters

r252470:
Count the number of hits for a filter by default.

r250697:
Add dependencies on the firmware, which allows the loading of the cxgb
and cxgbe modules.

248925 Sat Mar 30 00:34:15 MDT 2013 np cxgbe(4): Add support for Chelsio's Terminator 5 (aka T5) ASIC. This
includes support for the NIC and TOE features of the 40G, 10G, and
1G/100M cards based on the T5.

The ASIC is mostly backward compatible with the Terminator 4 so cxgbe(4)
has been updated instead of writing a brand new driver. T5 cards will
show up as cxl (short for cxlgb) ports attached to the t5nex bus driver.

diff 221407 Tue May 03 18:00:00 MDT 2011 marius - Remove attempts to implement setting of BMCR_LOOP/MIIF_NOLOOP
(reporting IFM_LOOP based on BMCR_LOOP is left in place though as
it might provide useful for debugging). For most mii(4) drivers it
was unclear whether the PHYs driven by them actually support
loopback or not. Moreover, typically loopback mode also needs to
be activated on the MAC, which none of the Ethernet drivers using
mii(4) implements. Given that loopback media has no real use (and
obviously hardly had a chance to actually work) besides for driver
development (which just loopback mode should be sufficient for
though, i.e one doesn't necessary need support for loopback media)
support for it is just dropped as both NetBSD and OpenBSD already
did quite some time ago.
- Let mii_phy_add_media() also announce the support of IFM_NONE.
- Restructure the PHY entry points to use a structure of entry points
instead of discrete function pointers, and extend this to include
a "reset" entry point. Make sure any PHY-specific reset routine is
always used, and provide one for lxtphy(4) which disables MII
interrupts (as is done for a few other PHYs we have drivers for).
This includes changing NIC drivers which previously just called the
generic mii_phy_reset() to now actually call the PHY-specific reset
routine, which might be crucial in some cases. While at it, the
redundant checks in these NIC drivers for mii->mii_instance not being
zero before calling the reset routines were removed because as soon
as one PHY driver attaches mii->mii_instance is incremented and we
hardly can end up in their media change callbacks etc if no PHY driver
has attached as mii_attach() would have failed in that case and not
attach a miibus(4) instance.
Consequently, NIC drivers now no longer should call mii_phy_reset()
directly, so it was removed from EXPORT_SYMS.
- Add a mii_phy_dev_attach() as a companion helper to mii_phy_dev_probe().
The purpose of that function is to perform the common steps to attach
a PHY driver instance and to hook it up to the miibus(4) instance and to
optionally also handle the probing, addition and initialization of the
supported media. So all a PHY driver without any special requirements
has to do in its bus attach method is to call mii_phy_dev_attach()
along with PHY-specific MIIF_* flags, a pointer to its PHY functions
and the add_media set to one. All PHY drivers were updated to take
advantage of mii_phy_dev_attach() as appropriate. Along with these
changes the capability mask was added to the mii_softc structure so
PHY drivers taking advantage of mii_phy_dev_attach() but still
handling media on their own do not need to fiddle with the MII attach
arguments anyway.
- Keep track of the PHY offset in the mii_softc structure. This is done
for compatibility with NetBSD/OpenBSD.
- Keep track of the PHY's OUI, model and revision in the mii_softc
structure. Several PHY drivers require this information also after
attaching and previously had to wrap their own softc around mii_softc.
NetBSD/OpenBSD also keep track of the model and revision on their
mii_softc structure. All PHY drivers were updated to take advantage
as appropriate.
- Convert the mebers of the MII data structure to unsigned where
appropriate. This is partly inspired by NetBSD/OpenBSD.
- According to IEEE 802.3-2002 the bits actually have to be reversed
when mapping an OUI to the MII ID registers. All PHY drivers and
miidevs where changed as necessary. Actually this now again allows to
largely share miidevs with NetBSD, which fixed this problem already
9 years ago. Consequently miidevs was synced as far as possible.
- Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that
weren't explicitly converted to support flow control before. It's
unclear whether flow control actually works with these but typically
it should and their net behavior should be more correct with these
changes in place than without if the MAC driver sets MIIF_DOPAUSE.

and the add_media set to one. All PHY drivers were updated to take
advantage of mii_phy_dev_attach() as appropriate. Along with these
changes the capability mask was added to the mii_softc structure so
PHY drivers taking advantage of mii_phy_dev_attach() but still
handling media on their own do not need to fiddle with the MII attach
arguments anyway.
- Keep track of the PHY offset in the mii_softc structure. This is done
for compatibility with NetBSD/OpenBSD.
- Keep track of the PHY's OUI, model and revision in the mii_softc
structure. Several PHY drivers require this information also after
attaching and previously had to wrap their own softc around mii_softc.
NetBSD/OpenBSD also keep track of the model and revision on their
mii_softc structure. All PHY drivers were updated to take advantage

- Convert the mebers of the MII data structure to unsigned where
appropriate. This is partly inspired by NetBSD/OpenBSD.
- According to IEEE 802.3-2002 the bits actually have to be reversed
when mapping an OUI to the MII ID registers. All PHY drivers and
miidevs where changed as necessary. Actually this now again allows to
largely share miidevs with NetBSD, which fixed this problem already
9 years ago. Consequently miidevs was synced as far as possible.
- Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that
weren't explicitly converted to support flow control before. It's
unclear whether flow control actually works with these but typically
it should and their net behavior should be more correct with these
changes in place than without if the MAC driver sets MIIF_DOPAUSE.

diff 221407 Tue May 03 18:00:00 MDT 2011 marius - Remove attempts to implement setting of BMCR_LOOP/MIIF_NOLOOP
(reporting IFM_LOOP based on BMCR_LOOP is left in place though as
it might provide useful for debugging). For most mii(4) drivers it
was unclear whether the PHYs driven by them actually support
loopback or not. Moreover, typically loopback mode also needs to
be activated on the MAC, which none of the Ethernet drivers using
mii(4) implements. Given that loopback media has no real use (and
obviously hardly had a chance to actually work) besides for driver
development (which just loopback mode should be sufficient for
though, i.e one doesn't necessary need support for loopback media)
support for it is just dropped as both NetBSD and OpenBSD already
did quite some time ago.
- Let mii_phy_add_media() also announce the support of IFM_NONE.
- Restructure the PHY entry points to use a structure of entry points
instead of discrete function pointers, and extend this to include
a "reset" entry point. Make sure any PHY-specific reset routine is
always used, and provide one for lxtphy(4) which disables MII
interrupts (as is done for a few other PHYs we have drivers for).
This includes changing NIC drivers which previously just called the
generic mii_phy_reset() to now actually call the PHY-specific reset
routine, which might be crucial in some cases. While at it, the
redundant checks in these NIC drivers for mii->mii_instance not being
zero before calling the reset routines were removed because as soon
as one PHY driver attaches mii->mii_instance is incremented and we
hardly can end up in their media change callbacks etc if no PHY driver
has attached as mii_attach() would have failed in that case and not
attach a miibus(4) instance.
Consequently, NIC drivers now no longer should call mii_phy_reset()
directly, so it was removed from EXPORT_SYMS.
- Add a mii_phy_dev_attach() as a companion helper to mii_phy_dev_probe().
The purpose of that function is to perform the common steps to attach
a PHY driver instance and to hook it up to the miibus(4) instance and to
optionally also handle the probing, addition and initialization of the
supported media. So all a PHY driver without any special requirements
has to do in its bus attach method is to call mii_phy_dev_attach()
along with PHY-specific MIIF_* flags, a pointer to its PHY functions
and the add_media set to one. All PHY drivers were updated to take
advantage of mii_phy_dev_attach() as appropriate. Along with these
changes the capability mask was added to the mii_softc structure so
PHY drivers taking advantage of mii_phy_dev_attach() but still
handling media on their own do not need to fiddle with the MII attach
arguments anyway.

- Keep track of the PHY's OUI, model and revision in the mii_softc

turned on and off via ifconfig(8) with the default typically
being off (though MIIF_FORCEPAUSE has been added causing flow
control to be always advertised, allowing to easily MFC this
changes for drivers that previously used home-grown support for
flow control that behaved that way without breaking POLA)

with manual selection doesn't work or at least isn't implemented,

NetBSD into mii_physubr.c and ukphy_subr.c. Unlike as in NetBSD,
IFM_FLOW isn't implemented as a global option via the "don't care

following advantages:
o allows flow control advertisement with autonegotiation to be
turned on and off via ifconfig(8) with the default typically
being off (though MIIF_FORCEPAUSE has been added causing flow
control to be always advertised, allowing to easily MFC this
changes for drivers that previously used home-grown support for
flow control that behaved that way without breaking POLA)
o allows to deal with PHY drivers where flow control advertisement
with manual selection doesn't work or at least isn't implemented,
like it's the case with brgphy(4), e1000phy(4) and ip1000phy(4),
by setting MIIF_NOMANPAUSE
o the available combinations of media options are readily available
from the `ifconfig -m` output
- Add IFM_FLOW to IFM_SHARED_OPTION_DESCRIPTIONS and IFM_ETH_RXPAUSE
and IFM_ETH_TXPAUSE to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so
these are understood by ifconfig(8).
o Make the master/slave support in mii(4) actually usable:
- Change IFM_ETH_MASTER from being implemented as a global option via
the "don't care mask" to a media specific one as it actually is only
applicable to IFM_1000_T to date.
- Let mii_phy_setmedia() set GTCR_MAN_MS in IFM_1000_T slave mode to

support for flow control but only if the selected media has IFM_FLOW
set (or MIIF_FORCEPAUSE is set) and implemented for these media variants,
i.e. typically only for copper.

and some IFM_FLAGn.
o Switch brgphy(4) to add at least the the supported copper media based on
the contents of the BMSR via mii_phy_add_media() instead of hardcoding
them. The latter approach seems to have developed historically, besides
causing unnecessary code duplication it was also undesirable because
brgphy_mii_phy_auto() already based the capability advertisement on the

diff 215297 Sun Nov 14 11:29:56 MST 2010 marius o Flesh out the generic IEEE 802.3 annex 31B full duplex flow control
support in mii(4):
- Merge generic flow control advertisement (which can be enabled by
passing by MIIF_DOPAUSE to mii_attach(9)) and parsing support from
NetBSD into mii_physubr.c and ukphy_subr.c. Unlike as in NetBSD,
IFM_FLOW isn't implemented as a global option via the "don't care
mask" but instead as a media specific option this. This has the
following advantages:
o allows flow control advertisement with autonegotiation to be
turned on and off via ifconfig(8) with the default typically
being off (though MIIF_FORCEPAUSE has been added causing flow
control to be always advertised, allowing to easily MFC this
changes for drivers that previously used home-grown support for
flow control that behaved that way without breaking POLA)
o allows to deal with PHY drivers where flow control advertisement
with manual selection doesn't work or at least isn't implemented,
like it's the case with brgphy(4), e1000phy(4) and ip1000phy(4),
by setting MIIF_NOMANPAUSE
o the available combinations of media options are readily available
from the `ifconfig -m` output
- Add IFM_FLOW to IFM_SHARED_OPTION_DESCRIPTIONS and IFM_ETH_RXPAUSE
and IFM_ETH_TXPAUSE to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so
these are understood by ifconfig(8).
o Make the master/slave support in mii(4) actually usable:
- Change IFM_ETH_MASTER from being implemented as a global option via
the "don't care mask" to a media specific one as it actually is only
applicable to IFM_1000_T to date.
- Let mii_phy_setmedia() set GTCR_MAN_MS in IFM_1000_T slave mode to
actually configure manually selected slave mode (like we also do in
the PHY specific implementations).
- Add IFM_ETH_MASTER to IFM_SUBTYPE_ETHERNET_OPTION_DESCRIPTIONS so it
is understood by ifconfig(8).
o Switch bge(4), bce(4), msk(4), nfe(4) and stge(4) along with brgphy(4),
e1000phy(4) and ip1000phy(4) to use the generic flow control support
instead of home-grown solutions via IFM_FLAGs. This includes changing
these PHY drivers and smcphy(4) to no longer unconditionally advertise
support for flow control but only if the selected media has IFM_FLOW
set (or MIIF_FORCEPAUSE is set) and implemented for these media variants,
i.e. typically only for copper.
o Switch brgphy(4), ciphy(4), e1000phy(4) and ip1000phy(4) to report and
set IFM_1000_T master mode via IFM_ETH_MASTER instead of via IFF_LINK0
and some IFM_FLAGn.
o Switch brgphy(4) to add at least the the supported copper media based on
the contents of the BMSR via mii_phy_add_media() instead of hardcoding
them. The latter approach seems to have developed historically, besides
causing unnecessary code duplication it was also undesirable because
brgphy_mii_phy_auto() already based the capability advertisement on the
contents of the BMSR though.
o Let brgphy(4) set IFM_1000_T master mode on all supported PHY and not
just BCM5701. Apparently this was a misinterpretation of a workaround
in the Linux tg3 driver; BCM5701 seem to require RGPHY_1000CTL_MSE and
BRGPHY_1000CTL_MSC to be set when configuring autonegotiation but
this doesn't mean we can't set these as well on other PHYs for manual
media selection.
o Let ukphy_status() report IFM_1000_T master mode via IFM_ETH_MASTER so
IFM_1000_T master mode support now is generally available with all PHY
drivers.
o Don't let e1000phy(4) set master/slave bits for IFM_1000_SX as it's
not applicable there.

like most other drivers. ppbus(4) only invokes the interrupt handler
of the device that currently owns the bus (if any) when an interrupt
occurs, however. Also, interrupt handlers in general now accept their
softc pointers as their argument rather than the device_t. Another
feature of the ppbus interrupt handlers is that they are called with
the parent ppc device's lock already held. This minimizes the number
of lock operations during an interrupt.
- Mark plip(4), lpt(4), pcfclock(4), ppi(4), vpo(4) MPSAFE.
- lpbb(4) uses the ppc lock instead of Giant.
- Other plip(4) changes:
- Add a mutex to protect the global tables in plip(4) and free them on

their interrupt handler during attach and tear it down during detach
like most other drivers. ppbus(4) only invokes the interrupt handler
of the device that currently owns the bus (if any) when an interrupt
occurs, however. Also, interrupt handlers in general now accept their
softc pointers as their argument rather than the device_t. Another
feature of the ppbus interrupt handlers is that they are called with
the parent ppc device's lock already held. This minimizes the number
of lock operations during an interrupt.
- Mark plip(4), lpt(4), pcfclock(4), ppi(4), vpo(4) MPSAFE.
- lpbb(4) uses the ppc lock instead of Giant.
- Other plip(4) changes:
- Add a mutex to protect the global tables in plip(4) and free them on
module unload.
- Add a detach routine.
- Split out the init/stop code from the ioctl routine into separate
functions.

- Allocate the I/O buffers at attach and detach rather than during
open and close as this simplifies the locking at the cost of
1024+32 bytes when the driver is attached.

concurrent read/write.

- To avoid having a bunch of locks that end up always getting acquired as
a group, give each ppc(4) device a mutex which it shares with all the
child devices including ppbus(4), lpt(4), plip(4), etc. This mutex
is then used for all the locking.
- Rework the interrupt handling stuff yet again. Now ppbus drivers setup
their interrupt handler during attach and tear it down during detach
like most other drivers. ppbus(4) only invokes the interrupt handler
of the device that currently owns the bus (if any) when an interrupt
occurs, however. Also, interrupt handlers in general now accept their
softc pointers as their argument rather than the device_t. Another
feature of the ppbus interrupt handlers is that they are called with
the parent ppc device's lock already held. This minimizes the number
of lock operations during an interrupt.
- Mark plip(4), lpt(4), pcfclock(4), ppi(4), vpo(4) MPSAFE.
- lpbb(4) uses the ppc lock instead of Giant.
- Other plip(4) changes:
- Add a mutex to protect the global tables in plip(4) and free them on
module unload.
- Add a detach routine.
- Split out the init/stop code from the ioctl routine into separate
functions.
- Other lpt(4) changes:
- Use device_printf().
- Use a dedicated callout for the lptout timer.
- Allocate the I/O buffers at attach and detach rather than during
open and close as this simplifies the locking at the cost of
1024+32 bytes when the driver is attached.

- Add a detach routine.
- Use a malloc'd buffer for each read and write to avoid races with
concurrent read/write.

- To avoid having a bunch of locks that end up always getting acquired as
a group, give each ppc(4) device a mutex which it shares with all the
child devices including ppbus(4), lpt(4), plip(4), etc. This mutex
is then used for all the locking.
- Rework the interrupt handling stuff yet again. Now ppbus drivers setup
their interrupt handler during attach and tear it down during detach
like most other drivers. ppbus(4) only invokes the interrupt handler
of the device that currently owns the bus (if any) when an interrupt
occurs, however. Also, interrupt handlers in general now accept their
softc pointers as their argument rather than the device_t. Another
feature of the ppbus interrupt handlers is that they are called with
the parent ppc device's lock already held. This minimizes the number
of lock operations during an interrupt.

module unload.
