Public bug reported:
SRU Justification:
[Impact]
The mlxbf_gige driver currently has three driver-managed
interrupt counts that increment each time every interrupt
handler executes. This has been reviewed and found to be
unnecessary given core logic in Linux kernel manages the
same information.
[Fix]
The fix is to remove the driver-managed interrupt counts
from the driver itself, and let the core handle it.
There is an upstream commit already that makes this change.
[Test Case]
The driver should function as before, specifically:
* driver probes successfully
* oob_net0 link comes up, as seen with "ifconfig -a"
[Regression Potential]
This change only affects counters that are visible inside
driver, so thus should not introduce any regression.
** Affects: linux-bluefield (Ubuntu)
Importance: Undecided
Status: New
