[PATCH net 1/4] bnxt_en: Perform function reset earlier during probe.
From: Michael Chan <michael.chan@broadcom.com>
Date: 2017-03-08 23:46:03
Subsystem:
broadcom bnxt_en 50 gigabit ethernet driver, networking drivers, the rest · Maintainers:

The firmware call to do function reset is done too late. It is causing
the rings that have been reserved to be freed. In NPAR mode, this bug
is causing us to run out of rings.
Fixes: 391be5c27364 ("bnxt_en: Implement new scheme to reserve tx rings.")
