Odd, that support is in the 0.9.14.9 hal that's in cvs. I noticed while
diff'ing that the tpc stuff wasn't in the driver but since that hal
doesn't do per-packet tpc correctly anyway it shouldn't matter. Turning
off diversity should reduce your performance; not improve it. I'd be
curious to see numbers for each change separately. It may be that the
antenna flipping logic is hurting you (it needs some fixups).

I would be curious to see if you're actually getting frames close to the
mtu. I just realized recently that I allowed the larger mtu but I think
the driver tosses frames larger than a cluster because the logic isn't
in the rx intr handler to chain rx descriptors (it is in another version
of code where I need it for Atheros' fast frames).
Turning off protection presumably means you're operating in 11g and only
supporting 11g stations? If so there's a better way to do this; just
set the pureg config so 11b stations are rejected by the ap.
