   3 Subject: vlan: device not reading gso max size of parent.
   4 References: FATE#303913
   5
   6 The vlan devices are not reading the gso max size of the parent device.  As
   7 a result devices that do not support 64K max gso size are currently
   8 failing.

  10 This issue is seen on 2.6.26 kernels as well and the same patch should be
  11 able to be applied without any issues.
