Subject: [PATCH net-next v2 1/4] ibmvnic: Account for VLAN tag in L2 Header descriptor
Date: Mon, 12 Mar 2018 11:51:02 -0500 [thread overview]
Message-ID: <1520873465-23312-2-git-send-email-tlfalcon@linux.vnet.ibm.com> (raw)
In-Reply-To: <1520873465-23312-1-git-send-email-tlfalcon@linux.vnet.ibm.com>
If a VLAN tag is present in the Ethernet header, account
for that when providing the L2 header to firmware.
