heas 2d4ced7c82 For controllers (eg: hme & gem) that can only perform linear hardware checksums 
(from an offset to the end of the packet), the pseudo-header checksum must be
calculated by software.  So, provide it in the TCP/UDP header when
M_CSUM_NO_PSEUDOHDR is set in the interface's if_csum_flags_tx.

The start offset, the end of the IP header, is also provided in the high 16
bits of pkthdr.csum_data.  Such that the driver need not examine the packet
at all.

XXX At the request of Jonathan Stone, note that sharing of if_csum_flags_tx &
    pkthdr.csum_flags for checksum quirks should be re-evaluated.
