Don't worry. If you will ever upgrade to 5.0, not only VLANs on FEC
interfaces, but FEC itself won't work.

Nice ASCII art. You can safely s/FreeBSD/Linux/g to get this work :~-(
(BTW, is it working under Linux? I don't use Linux)

ng_fec is in FreeBSD's tree starting from 5.0, but not yet connected to
the build. I assume it won't ever... :(

If anyone willing to fix it and can understand what's going on in the
kernel, I will gladly provide console (serial) access to a machine which
has two fxp NICs and is connected to a FEC aware switch.

Any takers?
