[13/17] net/bnxt: add more checks for fw reset
Checks
Commit Message
From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>
Added check for fw reset or fw errors in few more routines.
While processing the events, if it is fw fatal or non-fatal
event, there is no need to process the remaining events as
driver triggers recovery mechanism.
Also added a check for fw reset or fatal error in bnxt_disable_int()
to avoid bar access in case of fatal error.
