Title:

adapters
Status in linux package in Ubuntu:
Confirmed
Status in linux source package in Mantic:
Fix Committed
Status in linux source package in Noble:
Confirmed
Bug description:
[IMPACT]
This is requested by one of our larger server hardware partners and
Broadcom to to update the bnxt_en network driver code to add some bug
fixes and support for the newer 5760X adapters into Mantic. The goal
is to have these land in 22.04.4 HWE and the installer environment via
the HWE kernel.
Missing these patches will mean customers running this hardware will
not be able to use it with Ubuntu Server 22.04 LTS until the much
later 22.04.5 point release, setting up a months-long gap in support
for these adapters.
[FIXES]
These are all in mainline at 6.6-6.7 and linux-next queued for 6.8 and
pick cleanly with the exception of the two noted at the end of this
section. For Mantic all are picked. For Noble, only the subset
currently in linux-next will be picked, depending on what happens in
our Noble tree during the cycle.

These two requried backporting. The backport work was done by Michael
Chan @ Broadcom as noted by comments in the commit messages. This was
to resolve issues due to some missing prerequisite patches from
upstream that were not part of the bnxt code.

[TEST]
The changes added by these patches should have no negative impact on Broadcom
574XX and 575XX adapters. All tests that passed on those adapters before
adding these changes should continue to pass.
When a user runs 'modinfo bnxt_en' on this new driver entries for the
PCI IDs that represent this hardware should be found with the VID
0x14e4 and DIDs 0x1760, 0x1761, 0x1762, and 0x1763.
$ modinfo bnxt_en | grep 176
alias: pci:v000014E4d00001763sv*sd*bc*sc*i*
alias: pci:v000014E4d00001762sv*sd*bc*sc*i*
alias: pci:v000014E4d00001761sv*sd*bc*sc*i*
alias: pci:v000014E4d00001760sv*sd*bc*sc*i*
A test kernel based on these changes has been tested at Broadcom to
ensure the 5760X hardware functions as expected with this driver.
[Where Problems Might Occur]
Much of the code added in these patches is specific to 5760X. These have
been tested extensively in out-of-box form for quite a while and the upstream
versions have also been tested extensively by Broadcom's QA team prior and
after acceptance upstream. Areas of concern are centered around
non-standard/untested optics and higher link0speeds than were supported on
existing 574XX and 575XX devices.
