[dpdk-dev] [PATCH v2 1/6] net/bnxt: add missing checks for firmware reset

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com>

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")
