From faa89577621b4296a8869e75b90a546c951df968 Mon Sep 17 00:00:00 2001 From: Dai Haruki Date: Mon, 24 Mar 2008 10:53:26 -0500 Subject: [PATCH] gianfar: Fix frame size calculation when hardware VLAN acceleration is on In gfar_change_mtu(), the frame size needs to be increased to account for the extra 4 bytes VLAN adds to the ethernet header. However, it was being increased by the length of the whole header (18 bytes), which is wrong.
