I've seen some notes from Dave Miller about adding multiple TX queues
to the 2.6.27 kernel. See Dave's blog for the gory details:
http://vger.kernel.org/~davem/cgi-bin/blog.cgi
http://git.kernel.org/?p=linux/kernel/git/davem/net-tx-2.6.git;a=summary
AFAIK he hasn't made any claims about performance improvements. I
don't know the state of RX queues in Linux.
