[dpdk-dev] [PATCH 4/8] net/bnxt: allow Tx only or Rx only configs in PMD

[Kalesh A P]

From: Damodharam Ammepalli <damodharam.ammepall at broadcom.com>

Currently, we fail the init/probe of pmd if eth_dev->data->nb_tx_queues
or eth_dev->data->nb_rx_queues is 0. We are removing this check.

Fixes: daef48efe5e5 ("net/bnxt: support set MTU")
Cc: stable at dpdk.org
