[dpdk-stable] [PATCH 2/7] net/bnxt: reset Rx allocation state on Rx queue restart

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

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

Call bnxt_rxq_vec_setup() to ensure that rxq->rxrearm_nb and
rxq->rxrearm_start are initialized correctly when a receive
queue is restarted.

Fixes: bc4a000f2f53 ("net/bnxt: implement SSE vector mode")
