From a62bfb72b9ca4b0e3b1db5af125b63a16a3e507c Mon Sep 17 00:00:00 2001 From: Bruce Richardson Date: Tue, 23 Sep 2014 12:08:17 +0100 Subject: [PATCH] mbuf: switch vlan_tci and reserved2 fields Move the vlan_tci field up by two bytes in the mbuf data structure. This has two effects: * Ensures the the ixgbe vector driver places the vlan tag in the correct place in the mbuf. * Allows a second vlan tag field, if one is added in the future, to be placed after the existing vlan field, rather than before.
