Module Name:    src
Committed By:   tsutsui

Modified Files:
        src/sys/dev/ic: i82557.c

Log Message:
Computed checksum value by the FXPF_82559_RXCSUM feature includes data
in IP headers, so we have to deduct not only IP option headers but all
IP headers.  But in TCP/UDP layer we can assume the IP header is valid
and a sum of the IP header part should be 0xffff, so we don't have to
bother to deduct it from the computed checksum.
