Also, this help text is broken too.

I repeat: "THIS IS NOT A TIGON3 5701 NETWORK ADAPTER SPECIFIC HACK"

It is a config variable that all network drivers in the kernel can
test to make copybreak and related decisions for copy vs. read
directly packet handling.

Please stop making this a tigon3 specific thing.


We should CC David Mosberger on this, too. He's been wanting something like this (for, as you say, all network drivers) for a while now.
