re TSO: data corruption

[Anton Yuzhaninov]

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.

re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
         options=399b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_UCAST,WOL_MCAST,WOL_MAGIC>

     vendor     = 'Realtek Semiconductor'
     device     = 'RTL8169/8110 Family Gigabit Ethernet NIC'
     class      = network
     subclass   = ethernet

Known workaround:
ifconfig re0 -tso

May be TSO should be disabled by default?

System is fresh:
