[dpdk-stable] [PATCH 3/6] net/enic: set Rx VLAN offload flag for non-stripped packets

[John Daley]

From: Hyong Youb Kim <hyonkim at cisco.com>

The NIC indicates VLAN TCI to the driver even when VLAN stripping is
disabled. The driver sets mbuf's vlan_tci but not PKT_RX_VLAN. Set
PKT_RX_VLAN to indicate that vlan_tci is valid.
