Problem Details: Maybe it's just me but I guess those md5 people made a mess out of it by having *_md5_hash_* to use daddr, saddr order instead of the one that is natural (and equal to what csum functions use). For the segment were sending, the original addresses are reversed so buff's saddr == skb's daddr and vice-ver...
