Actually no; at least not in 4.2-R. See the following PR:

	 http://www.FreeBSD.org/cgi/query-pr.cgi?pr=11525

Those issues weren't exactly related to performance (bandwidth),
but they can cause a lot of network functions (rpc, mrouted, etc.)
to either not working correctly, or not working at all when you
have dynamically attached Ethernet interfaces (PCMCIA NICs) plus
a lot ( > 32) of virtual interfaces (gif, tun).

We emailed a follow-up to the list a few months back regarding the
PR, but didn't hear anything. Guess people don't use that many gifs
in their notebooks. :-)
