From: Lance Richardson Date: Fri, 19 Jul 2019 06:19:04 +0000 (+0530) Subject: net/bnxt: disable vector mode Tx with VLAN offload X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=fca922e8f602c5acc0c483296c769fd2a9efa48c;p=dpdk.git net/bnxt: disable vector mode Tx with VLAN offload 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.
