# 286272 04-Aug-2015 np

MFC r284984:

cxgbetool: fix code that decodes T5 SGE contexts. Some of the fields
that changed between T4 and T5 were not displayed correctly.


# 274615 17-Nov-2014 np

MFC r273360:

One of MAP_ANON, MAP_PRIVATE, MAP_SHARED, or MAP_STACK must be specified.


# 269357 31-Jul-2014 np

MFC r269106:

Add a 'raw' parameter to the 'modinfo' subcommand. This is handy when
trying to figure out why a QSFP+/SFP+ connector or cable wasn't
identified correctly by cxgbe(4). Its output looks like this:

# cxgbetool t5nex0 modinfo 0 raw
00: 03 04 21 00 00 00 00 00 ..!. ....

# 265415 06-May-2014 np

MFC r261534:
cxgbetool: Display the congestion channel map in hex.


# 259142 09-Dec-2013 np

MFC r257654, r257772, r258441, r258689, r258698, r258879, r259048, and
r259103.

r257654:
cxgbe(4): Exclude MPS_RPLC_MAP_CTL (0x11114) from the register dump. Turns
out it's a write-only register with strange side effects on read.

r257772:
cxgbe(4): Tidy up the display for payload memory statistics (pm_stats).

r258441:
cxgbe(4): update the internal list of device features.

r258689:
Disable an assertion that relies on some code[1] that isn't in HEAD yet.

r258698:
cxgbetool: "modinfo" command to display SFP+ module information.

r258879:
cxgbe(4): T4_SET_SCHED_CLASS and T4_SET_SCHED_QUEUE ioctls to program
scheduling classes in the chip and to bind tx queue(s) to a scheduling
class respectively. These can be used for various kinds of tx traffic
throttling (to force selected tx queues to drain at a fixed Kbps rate,
or a % of the port's total bandwidth, or at a fixed pps rate, etc.).

r259048:
Two new cxgbetool subcommands to set up scheduler classes and to bind
them to NIC queues.

r259103:
cxgbe(4): save a copy of the RSS map for each port for the driver's use.


# 256281 10-Oct-2013 gjb

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

# 253870 01-Aug-2013 np

Teach cxgbetool to display T5 congestion manager context.


# 253691 26-Jul-2013 np

Add support for packet-sniffing tracers to cxgbe(4). This works with
all T4 and T5 based cards and is useful for analyzing TSO, LRO, TOE, and
for general purpose monitoring without tapping any cxgbe or cxl ifnet
directly.

Tracers on the T4/T5 chips provide access to Ethernet frames exactly as
they were received from or transmitted on the wire. On transmit, a
tracer will capture a frame after TSO segmentation, hw VLAN tag
insertion, hw L3 & L4 checksum insertion, etc. It will also capture
frames generated by the TCP offload engine (TOE traffic is normally
invisible to the kernel). On receive, a tracer will capture a frame
before hw VLAN extraction, runt filtering, other badness filtering,
before the steering/drop/L2-rewrite filters or the TOE have had a go at
it, and of course before sw LRO in the driver.

There are 4 tracers on a chip. A tracer can trace only in one direction
(tx or rx). For now cxgbetool will set up tracers to capture the first
128B of every transmitted or received frame on a given port. This is a
small subset of what the hardware can do. A pseudo ifnet with the same
name as the nexus driver (t4nex0 or t5nex0) will be created for tracing.
The data delivered to this ifnet is an additional copy made inside the
chip. Normal delivery to cxgbe<n> or cxl<n> will be made as usual.

/* watch cxl0, which is the first port hanging off t5nex0. */
# cxgbetool t5nex0 tracer 0 tx0 (watch what cxl0 is transmitting)
# cxgbetool t5nex0 tracer 1 rx0 (watch what cxl0 is receiving)
# cxgbetool t5nex0 tracer list
# tcpdump -i t5nex0 <== all that cxl0 sees and puts on the wire

If you were doing TSO, a tcpdump on cxl0 may have shown you ~64K
"frames" with no L3/L4 checksum but this will show you the frames that
were actually transmitted.

/* all done */
# cxgbetool t5nex0 tracer 0 disable
# cxgbetool t5nex0 tracer 1 disable
# cxgbetool t5nex0 tracer list
# ifconfig t5nex0 destroy


# 252470 01-Jul-2013 np

Count the number of hits for a filter by default.

# 249368 11-Apr-2013 np

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

# 248925 30-Mar-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.

# 247854 05-Mar-2013 np

Fix compile warning by including ctype.h for isdigit().

MFC after: 1 day


# 245520 17-Jan-2013 np

Allow "ivlan" (inner VLAN) to be used as an alias for "vlan" when
specifying match criteria. "vlan" continues to be valid here, and it
continues to be valid when deleting, rewriting, inserting, or stacking
an 802.1q tag to a matching packet.

# 241416 10-Oct-2012 np

Add a "clearstats" subcommand to cxgbetool that lets you clear the
MAC statistics for any port.

For example:
# cxgbetool t4nex0 clearstats 0

# 241401 10-Oct-2012 np

Add an "i2c" subcommand to cxgbetool. You can use this to read
information from the transceivers connected to the ports of a
cxgbe(4) based card.

# cxgbetool t4nex0 i2c <port_id> <dev_addr> <addr> [<count>]

For example:
# cxgbetool t4nex0 i2c 0 0xa0 3
0x10 [16]

(As per SFF-8472 the SFP+ module is at 0xa0 and bit 4 in the value at
address 3 indicates it's a 10Gbase-SR module, which it is.)


# 228594 16-Dec-2011 np

Catch up with new driver ioctls in cxgbe.

MFC after: 1 month


# 228561 16-Dec-2011 np

Many updates to cxgbe(4)

- Device configuration via plain text config file. Also able to operate
when not attached to the chip as the master driver.

- Generic "work request" queue that serves as the base for both ctrl and
ofld tx queues.

- Generic interrupt handler routine that can process any event on any
kind of ingress queue (via a dispatch table).

- A couple of new driver ioctls. cxgbetool can now install a firmware
to the card ("loadfw" command) and can read the card's memory
("memdump" and "tcb" commands).

- Lots of assorted information within dev.t4nex.X.misc.* This is
primarily for debugging and won't show up in sysctl -a.

- Code to manage the L2 tables on the chip.

- Updates to cxgbe(4) man page to go with the tunables that have changed.

- Updates to the shared code in common/

- Updates to the driver-firmware interface (now at fw 1.4.16.0)
