[dpdk-dev] [PATCH 1/3] net/bnxt: fix Rx mbuf VLAN in scalar Rx

[Kalesh A P]

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

In the scalar Rx path, for the VLAN packet, TCI is not saved in
the "mbuf->vlan_tci", however the STRIPPED offload flag is set
along with PKT_RX_VLAN flag.

[dpdk-dev] [PATCH 2/3] net/bnxt: check FW capability for VLAN offloads

[Kalesh A P]

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

VLAN offload capability may be disabled in the FW. The driver
should not attempt to override or utilize this feature in such
scenarios since it will not work as expected.
