Re: RFC: Evolution of the em driver

on if_em and have two (or more drivers) that support their hardware
families well instead of one driver that supports multiple families
marginally.

For what it's worth, I agree with Scott. I'd rather see a new and
separate driver (presumably igb(4)) than a "hacked up" em(4) driver
trying to handle tons of IC revisions. A good example of the insanity
the latter causes is nve(4) vs. nfe(4). :-)
