cdc-eem: bad crc checking
When the driver received an EEM packet with CRC option enabled, driver must compute and check the CRC of the Ethernet data. Previous version computes CRC on Ethernet data plus the original CRC value. Skbuff is correctly trimed but the old length is used when CRC is computed. Signed-off-by: Vincent CUISSARD <vincent.cuissard@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
