[tulip] Permanent interrupt mitigation with 21143 quad card

Just a quick followup on my experiences with Ben's patch:

With the patch applied to the 2.4.20-rc1 kernel (though I imagine you
could reproduce the results on any of the 2.4.19 kernels as well), I'm
now able to obtain full speed (~95 Mbps) routing with all interfaces
active on my 21143-based quad card.  If any of you out there are trying
to do something similar for a network testbed of some kind and want to
give the patch a try, I've made it available for download from
http://halo-x.wox.org/download/misc/tulip_2.4.19.patch.  Enjoy :).

Please let the list know, it might induce folks to think about applying
the patch to the main kernel :)

What NICs are you using, btw?
