The ibmveth driver is a virtual Ethernet driver used on IBM pSeries systems.
Gso packets can be sent between LPARS (virtual hosts) without segmentation,
by flagging gso packets using one of two methods depending on the firmware
version. Some gso packet were not correctly identified by the receiver.
This patch-set corrects this issue.

V2:
- Added fix tags.
- Byteswap the constant at compilation time.
- Updated the commit message to clarify what frame validation is performed
  by the hypervisor.
