From 83636580ad99cffd85b07e75da7ad45ada0fd530 Mon Sep 17 00:00:00 2001 From: Doug Kehn Date: Wed, 11 Jan 2012 13:12:43 +0000 Subject: [PATCH] ksz884x: fix mtu for VLAN The Ethernet header does not account for the addition of a VLAN header. Full size Ethernet frames containing VLAN header are not processed because the frame is larger than the resulting hw mtu. Signed-off-by: Doug Kehn Signed-off-by: David S.
