vxge: Disable fcs stripping.
- Disable fcs stripping. The minimum frame size that can be received by the
hardware is 57 Bytes. A 64 Byte Ethernet frame with the vlan tag and fcs
stripped will result in a 56 Byte frame which will lock up the receive
engine. The work around is to disable fcs stripping in the hardware which
is done with a firmware upgrade. The fixes are -
1. Ensure that the correct firmware version is used.
2. Decrement the indicated packet length of the receive packet by 4 bytes
(FCS length).
