ifconfig fxp0 link0 from rc.conf?

[Matthew Herzog]

What is the proper way to turn on the checksum offloading for an Intel
fxp card?

Yes, it's obvious I can do it by hand with ifconfig. That works fine.
How do enable it in rc.conf so that
it happens upon each reboot? I searched the www for an hour and found no
examples.

My guess would be -flags link0 but I'd rather be sure before hosing the
interface on this physically remote machine ;)

Thanks.
