From 6e5eed042fcac4166874d25cf9fb89bee841eb26 Mon Sep 17 00:00:00 2001 From: "Lendacky, Thomas" Date: Tue, 24 Jun 2014 16:19:12 -0500 Subject: [PATCH] amd-xgbe: VLAN Tx tag insertion fix The MAC_VLAN_Incl register (0x0060) must be set to indicate that the VLAN tag to be inserted comes from a Tx context descriptor and not the MAC_VLAN_Incl register. Also, even though it is the default, explicitly set the type of tag to be inserted as a CTAG. Signed-off-by: Tom Lendacky Signed-off-by: David S.
