When TSO enabled on my re NIC, data transferred via network corrupted.
It easy to reproduce using scp:
citrin:~>scp some_file.tar.bz2 some_host:
..
Received disconnect from 10.10.10.100: 2: Corrupted MAC on input.
lost connection
And same when data transferred to any other host.

Known workaround:
ifconfig re0 -tso
May be TSO should be disabled by default?
