Date: Wed, 11 Jan 2012 12:21:46 -0800 (PST) From: Doug Kehn <rdkehn@...oo.com> To: "netdev@...r.kernel.org" <netdev@...r.kernel.org> 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.
