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.

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?


On anything coming from Realtek? Probably. Certainly not in general.
