[dpdk-dev] [PATCH 3/3] net/bnxt: fix VLAN indication in Rx mbuf

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil at broadcom.com>

Fix to ignore the RX_PKT_CMPL_FLAGS2_META_FORMAT_VLAN
when the firmware doesn't support the VLAN strip offload.

Fixes: 2eb53b134aae ("net/bnxt: add initial Rx code")
Cc: stable at dpdk.org
