[PATCH net-next 0/3] eth: bnxt: handle invalid Tx completions more gracefully

[Jakub Kicinski <kuba@kernel.org>]

bnxt trusts the events generated by the device which may lead to kernel
crashes. These are extremely rare but they do happen. For a while
I thought crashing may be intentional, because device reporting invalid
completions should never happen, and having a core dump could be useful
if it does. But in practice I haven't found any clues in the core dumps,
and panic_on_warn exists.

Series was tested by forcing the recovery path manually. Because of
how rare the real crashes are I can't confirm it works for the actual
device errors until it's been widely deployed.

Jakub Kicinski (3):
  eth: bnxt: move and rename reset helpers
  eth: bnxt: take the bit to set as argument of bnxt_queue_sp_work()
  eth: bnxt: handle invalid Tx completions more gracefully
