I can reliable reproduce this. When I disable tso, the transfers complete and I
have no more OOW messages in my logs.
My /etc/ipf.rules:
pass in quick on lo0 all
pass out quick on lo0 all
block in log first all
pass in quick proto tcp from 84.22.102.2/32 to any port = 22 flags S keep state
pass out quick keep state
