Public bug reported:
SRU Justification:
[Impact]
The ipmb driver failing to load is just the result of i2c-mlxbf
not receiving interrupts.
In fact, any driver dependent on the i2c-mlxbf driver will not work.
How to reproduce this issue?
- modprobe gpio-mlxbf3

Reopening this bug since we found a software workaround for it.

During the reboot test, QA found an intermittent issue where the OOB link is
down.
The link is down because the KSZ9031 PHY fails to complete autonegotiation.
Even under "normal" circumstances where autonegotiation completes,
it takes an

Title:
mlxbf-gige: support fixed phy for Bobcat
Public bug reported:
SRU Justification:
[Impact]
Bobcat is a new board which doesn't have an external PHY connected to
the OOB. There are no MDIO busses involved and no PHY involved. The OOB
is directly connected to the switch (MAC to MAC). SO we need to use the
linux fixed phy to be able to

At the moment, the mlxbf-gige is broken in the ubuntu image because it is out
of date. This change in the gpio-mlxbf2.c driver broke it:

Although the gpio-mlxbf2.c driver has already been upstreamed, it did not
include gpio interrupt handling. We recently upstreamed the latter and as
requested by maintainers, moved all gpio interrupt code from the mlxbf-gige
driver to the

The BlueSphere like boards have a feature where the BMC
can trigger a BlueField ARM reset via ipmitool. The ipmitool
command simply toggles the signal on a BMC GPIO pin which
propagates to HOST GPIO 7. HOST GPIO 7 is setup as an
