Sadly thats the small picture view that has plagued freebsd for
the longest time. The bigger picture is that big OEMs aren't going
to use chelsio cards, and big OEMs running FreeBSD instead of linux
mean more testers, more hardware, more code give-backs and more 
money for the project.

You don't really know how good or bad intel or broadcom is because
you don't have good drivers for the cards. Unfortunately Intel does
things ass-backwards, by putting out crap "sample" drivers that make
their cards look like garbage. Maybe they are garbage, but you think
 they'd be a bit smarter. They can certainly afford more than Chelsio.
