[dpdk-stable] [PATCH v2 2/4] net/bnxt: keep consistent rxq start/stop state

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

From: Lance Richardson <lance.richardson@broadcom.com>

Receive queue state needs to reflect "started" state when rebuilding
the RSS table for Thor-based NICs. Move state update so that receive
queues being started are included in the RSS table.

Fixes: 38412304b50a ("net/bnxt: enable RSS for thor-based controllers")
