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).
