Subject: net/bnxt: add checks for firmware reset
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=aadae082ee46be8e6800a53a316eca558a31d103;p=dpdk.git

net/bnxt: add checks for firmware reset

Driver should fail the eth_dev_ops callbacks and accessing
Tx and Rx queues when device is in reset or in error state.
Added missing checks for fw reset in few routines.

Fixes: be14720def9c ("net/bnxt: support FW reset")
