From: Hannes Reinecke Date: Wed, 17 Sep 2008 16:44:46 +0200 Subject: vlan: device not reading gso max size of parent. References: FATE#303913 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.
