[dpdk-dev] [PATCH 5/7] net/bnxt: disable vector mode Tx with VLAN offload

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

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

The vector mode transmit path does not currently support VLAN tag
insertion, so we need to disable vector transmit when transmit
VLAN insertion offload is enabled.

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