From 1ae4be22f64326a6784acd7083b9590c9f4215a2 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Thu, 11 Sep 2008 20:17:05 -0700 Subject: [PATCH] vlan: vlan device not reading gso max size of parent. The vlan devices are not reading the gso max size of the parent device. As a result devices that do not support 64K max gso size are currently failing. This issue is seen on 2.6.26 kernels as well and the same patch should be able to be applied without any issues. Signed-off-by: Alexander Duyck Signed-off-by: Jeff Kirsher Signed-off-by: David S.
