Subject: Fix a typo with TSO logic in ip6_output().  Of course compare ph_mss
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=5de035283b4b7f23a27847b6e4011bc3e2da7984;p=openbsd

Fix a typo with TSO logic in ip6_output().  Of course compare ph_mss
with if_mtu and not the packet checksum flags.  ph_mss contains the
size of the copped packets.
OK jan@
