When I send a vlan packet, in driver, when we extract ether_type from ether_header in mbuf, for vlan packets ether_type is not set to ETHERTYPE_VLAN.

To test, we can use Emulex Skyhawk adapter. In OCE Inbox driver, in oce_tso_setup(), ether_type is not coming as ETHERTYPE_VLAN for vlan packets.

Below are the steps to create vlan interface
ifconfig oce0 up
ifconfig vlan0 create
ifconfig vlan0  vlan 4 vlandev oce0
ifconfig vlan0 40.4.4.98 up

Hi,

Does MFC'ing this patch to 10-stable solve the issue?
