I've only been using it for a few hours, but it is clearly better
than what was in my -CURRENT snapshot from this morning. Measuring
using speedof.me, I got about a 25% increase in download speed and
about a 35% increase in upload speed. There's some uncertainty
because I'm using a crowded 2.4 GHz spectrum and sometimes it's
more congested than at other times. Subjectively, it feels a lot
better when browsing the web, FWIW.
For some reason, iwm has never used the much less congested 5GHz
band that Linux uses on the same machine, resulting in only a
small fraction of the speed I get when I am booted into Linux
(this is not a change caused by your patch). Your patch makes the
connection usable for me. Nice work! :)
