net: NETIF_F_HW_CSUM does not imply FCoE CRC offload
commit 66c68bcc489fadd4f5e8839e966e3a366e50d1d5 upstream.
NETIF_F_HW_CSUM indicates the ability to update an TCP/IP-style 16-bit
checksum with the checksum of an arbitrary part of the packet data,
whereas the FCoE CRC is something entirely different.
