Thanks Bernhard for all the additional info about the current state
of the iwn driver.
I still do have a couple more small questions however.
First it really does appear to me that even when my iwm0 device is
successfully connecting to an AP which has been set to do "N-only",
the information that is displayed via "ifconfig -a" is still showing
it as if it were communicating using 11g:

Should I file a PR on this small problem/issue?
Second, and again based on the output shown via "ifconfig -a", it
appears to me that even when it is in `N' mode (and even when my AP is
set to "auto" selection of either 40 or 20Mhz channels), the card
is never managing to get above 54Mbps, tops (and often considerably less,
as you can see above).
So what am I doing wrong exactly? I had been trying some different equipment
earlier, but in the same locations and at the same distance, and in that case
I was routinely getting between 117Mbps and as much as 130Mbps... or anyway,
so said dd-wrt.
Ultimately, I want to stream HD out to the laptop that has the Intel 5100
in in, and thus, I really would like to get something above 54Mbps. And
it seems to me that this _should_ be possible. (In theory, I should be able
to get all of the way to 150Mbps, right?) So why can't I get my iwn0 device
(Intel 5100) under FreeBSD going anywhere near that fast?

rfg
