Seriously Pavel, give me a break. I already responded pretty quickly to this
bug report, took a look at where the issue could be and proposed a fix
(which Ivaylo tested successfully). Now, wireless drivers are *waay* outside
my area of expertise, so I added some other folks to CC in the hope that
they could help turn my fix into something upstreamable. Meanwhile, Ivaylo
looks like he has something better than what I came up with already.

If you care about this driver, why don't you help us fix it rather than
making unhelpful suggestions from the sidelines?
