net offloading: Accept NETIF_F_HW_CSUM for all protocols.
We currently only have software fallback for one type of checksum: the TCP/UDP one's complement. This means that a protocol that uses hardware offloading for a different type of checksum (FCoE, SCTP) must directly check the device's features and do the right thing ahead of time. By the time we get to dev_can_checksum(), we're only deciding whether to apply the one algorithm in software or hardware. NETIF_F_HW_CSUM has the same capabilities as the software version, so we should always use it if present. The primary advantage of this is multiply tagged vlans can use hardware checksumming.
