This is an alternate solution to the EEM 'sentinel' CRC valiation issue.
CDC EEM allows using a 'sentinel' ethernet frame CRC of 0xdeadbeef in
place of a real CRC. The 'sentinel' value is transmitted in big-endian
order whereas the normal CRC is little-endian. This patch handles both
cases appropriately.
