I've tested this trough several reboots, and I haven't been bitten by
any watchdogs yet. :)  I'll run some stress tests today, to see if it
handles that too.

I'm using re's default settings, which seem to be:

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>

So TSO for IPv4 but not IPv6, right?  I haven't yet seen any problems
because of it.  What would be a good way to "exercise" TSO?
