freebsd_network: Move up Giant ownership during attach.

device_attach can be recursed for MIIbus drivers, so avoid the complexity
and lock Giant from init_drivers() instead.

freebsd_network: Always hold the "Giant" lock during attaches.

Reduces patches to OpenBSD drivers slightly, and could potentially
help with some of the KDLs.

freebsd_network: PCI handling cleanup in preparation for USB support.

Should not have any functional change.

compat/freebsd_network: Fix Use of zero-allocated memory

If device is not found, 'list' is allocated to size 0.
So, modify function to return 0 as FreeBSD's subr_bus.c
when 'count' is 0.

Optimize ffs() implementation

- Use gcc builtin
- Define as a static inline function in the .h so no function call overhead is needed
- Keep the function in libroot for backwards compatibility
- Remove a duplicate implementation in the freebsd compatibility layer

gcc2 does not document the builtin, but it is in fact already available
there as well.

Fixes #3281.

freebsd_network: Moderate reorganization.

* Rename device.c to device_hooks.c, as this is what it really contains.
* Rename compat.c to device.c, as it implements the generic "device"
related functions, both for compat layer internals and FreeBSD
public ones.
* Move malloc and related operations out of the now-device.c,
and place them in a new "malloc.cpp", which also incorporates
compat_cpp.cpp.

No functional change intended.

freebsd11_network -> freebsd_network.

FreeBSD 12 has no major changes to the ifnet KPIs that constitute a
source compatibility break, save a single one related to locking
which doesn't really apply to us, and so we don't need to create
a "freebsd12_network" directory to work through the upgrades.

freebsd11_network: Actually set numBytes instead of silently truncating it.

If numBytes was greater than MCLBYTES (presently 1 << 11 = 2048), then the data beyond
MCLBYTES would be silently discarded instead of being written. Now, we store the
result of the min_c in numBytes, so the caller knows how much was written.

I turn on the printf that's commented out here and found that in practice this
seems to never happen (it's larger than the ethernet limit), so it seems unlikely
to fix any "transmission mysteriously failed" bugs.

Also backported this to the FreeBSD 9 layer.

FreeBSD compat layer: try 10BaseT if setting autoselect failed.

* This fixes PCnet Fast III on VirtualBox with pcn driver (#10088).

Reopening FreeBSD's compat devices was broken due to a missing flag
clear. Patch part of #7040. Thanks.

Avoid trying to set the media to Ethernet for WLAN devices.

It didn't really harm, but would always try to find a corresponding
media, fail and print an error.

Fixed up network stack and drivers for x86_64.

* Various compilation fixes.
* Fixes to the FreeBSD compatibility layer (from comparing the x86-
specific bits with the equivalent amd64 sources in FreeBSD).
* Compile all the Ethernet drivers except for sis900 and wb840, these
require a bit more work to fix (will file a ticket soon). Tested
ipro1000 and rtl81xx, no issues.

Fixed a few regressions that were introduced during the last months:
* device_attach() must not load the network stack. Besides being completely
unbalanced, this was also one reason why the stack could not be unloaded
anymore. Instead, it's now done in compat_open(), as before.
* This also fixes network booting from FreeBSD drivers - the stack apparently
could not be initialized that early.
* Replaced the previous network stack based callout implementation with one
that mostly copies its functionality, but has no dependencies. Furthermore,
it runs at a higher priority (the one of the network timer should also be
revisited, though).
* Fixed mtx_owned() to work without KDEBUG as well. It's not a good idea to
introduce code that behaves completely different based on debug settings.
* Minor cleanup.

Completely renovated the FreeBSD compatibility layer:
* Removed NETDEV() and DEVNET() macros and functionality.
* The exported devices are now attached to ifnet objects only, therefore, the
ifnet object now has the receive queue, and everything else a device could
need.
* There is now a root device where everything else is attached, it currently
only holds the pci_info structure, so it's more or less a PCI child.
* This simplified the device handling a bit everywhere.
* We now attach drivers already in init_driver() - this is needed as drivers
may publish more than one interface when being attached.
* Implemented device_delete_child(), device_attach() (which bus_generic_attach()
now uses), device_is_attached(), and device_is_alive().
* Therefore, if_initname() does now the actual job of registering the devices.
* On open, if_init() is called which comes pretty close to what our open()
is supposed to do.
* Updated ukphy.c to the one from FreeBSD 7 where used (we should probably
move that into the compat layer, anyway).
* The MII driver array must now be NULL terminated; therefore you don't need
to specify the count anymore.
* Moved PCI code from compat.c to bus.c.
* Moved the driver code from device.c to driver.c.
* Removed superfluous init_compat_layer() function.
* Fixed a few bugs, a few things weren't brought down correctly.
* The rtl8139 interrupt routine now checks if it really was the cause of the
interrupt - this code is not tested, either, it may not work (which would
then require a work-around like I did for the 3com driver).
* The HAIKU_PROTECT_INTR_REGISTER in the rtl8139 driver was pretty much useless
which is why I removed it.
* Probably introduced a lot of new bugs, though - I haven't tested this code
at all yet. It will probably just crash :-)

* Updated the FreeBSD compatibility layer for network drivers to FreeBSD 7
(RELENG_7_BP).
* There are many white spots, though, most notable PCI MSI(-X) support, and
jumbo frames.
* Fixed removing interrupts for the INTR_FAST case. Since FreeBSD 7 added
a new interrupt "filter" mechanism, we can finally report if the interface
was handled by a device or not (though only very few devices support this
yet).
* Updated the 3com, rtl8139, e1000, and via_rhine drivers to the latest code
base. They all compile, but I haven't tested them after the changes yet!

print anything.
* Added (commented out) debug output to compat_control().
* Renamed variables "len" to "length" where possible.
* Minor cleanup.

* Added miibus_linkchg and miibus_mediainit methods to device_set_driver(); this was the actual
reason the MII bus did not work as mediainit was never called.
* Got rid of the delayed MII bus scanning again; not only did it not solve the problem, it was
also completely unnecessary.
* Minor cleanup.

* Fixed the KASSERT() macro - it panicked without reason.
* Fixed device_set_driver(): it needs to clear the allocated buffer (it's
allocated with M_ZERO in FreeBSD).
* The first mbuf buffer needs to have the M_PKTHDR flag set.
* With these changes, the 3com driver now fails where it should have failed
before, that is in the missing interrupt handling.
* Minor cleanup.

* There are many white spots, though, most notable PCI MSI(-X) support, and
jumbo frames.
* Fixed removing interrupts for the INTR_FAST case. Since FreeBSD 7 added
a new interrupt "filter" mechanism, we can finally report if the interface
was handled by a device or not (though only very few devices support this
yet).
* Updated the 3com, rtl8139, e1000, and via_rhine drivers to the latest code
base. They all compile, but I haven't tested them after the changes yet!

First cut at a fix to the FreeBSD rtl9139 driver. Some drivers require softc to
be initialized when probe(0 is called. The driver now loads and works for a
while until it hangs. Looking into it.

* Calmed down the FreeBSD drivers even more - compat_{read|write}() no longer
print anything.
* Added (commented out) debug output to compat_control().
* Renamed variables "len" to "length" where possible.
* Minor cleanup.

* Added miibus_linkchg and miibus_mediainit methods to device_set_driver(); this was the actual
reason the MII bus did not work as mediainit was never called.
* Got rid of the delayed MII bus scanning again; not only did it not solve the problem, it was
also completely unnecessary.
* Minor cleanup.

Delayed scanning the MII bus until the first ifm_media has been set for the
device.

* Fixed the KASSERT() macro - it panicked without reason.
* Fixed device_set_driver(): it needs to clear the allocated buffer (it's
allocated with M_ZERO in FreeBSD).
* The first mbuf buffer needs to have the M_PKTHDR flag set.
* With these changes, the 3com driver now fails where it should have failed
before, that is in the missing interrupt handling.
* Minor cleanup.

IFT_ETHER expects an arpcom structure at if_l2com; this would actually need
to be expanded for other types, but for now, we'll probably only get IFT_ETHER
anyway.

freebsd compat. layer: fixed ETHER_GETFRAMESIZE handling. possible fix for #1238.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21195 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: MII subsystem (needs testers, more to come).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21097 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: implemented miibus_readreg and miibus_writereg, it goes up through the tree until the driver.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21095 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: split device structure to handle for miibus devices, added a new network_device.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21094 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: when open()ing the device, and setting it up, don't clear the device flags (multicast included).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21082 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: multicast support.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21081 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: close() and free().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21078 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: a couple more changes. a DMA-using driver (FreeBSD's em, Intel Pro 1000) now works without any modifications (it has a fast interrupt mode).


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21076 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: added a requirements field so not all drivers init all subsystems. pcnet for instance doesn't need taskqueues.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21072 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: taskqueue implementation.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21071 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: a few more definitions, preparing for a DMA-using driver.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21067 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: added ETHER_SETPROMISC, ETHER_GET_LINK_STATE and ETHER_SET_LINK_STATE_SEM support.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21050 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: now both receiving and sending work with PCNET.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21048 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: couple fixes, sending now works with PCNET. enabled ifmedia_ioctl, and when opening a device, set it down, change media to ETHER/AUTO and set it back up so it sees a IFF_UP.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21047 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: instead of disabling the IRQ, disable the device's interrupts on real interrupt request as suggested by Travis. This solves potential issues with shared IRQs. The check & disable interrupts function is part of the required glue code.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21045 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: use a thread for deferred interrupt handling. fixed a issue with bus_space_write_N. init the receive queue on device creation.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21041 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: added open(), which calls into the driver's attach. when testing with PCNET, a interface is already presented to the stack, it is even able to obtain the MAC address from the device, but still more work to do.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21030 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: we now init the several sub-parts through init_hardware, as well as allocate the available device_ts.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21029 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: use m_defrag to get a contiguous mbuf when read()ing. also added write() and a partial control().


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21028 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: a few more methods, preparing for pcnet


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21026 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: now the glue code properly references the required methods so we have proper linkage with gcc 4


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21017 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer: some initial glue code


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21013 a95241bf-73f2-0310-859d-f6bbb57e9c96

freebsd compat. layer, a few more methods.
