Subject: pull request: wireless-2.6 2008-06-09

Dave,

Here is another round of fixes intended for 2.6.26.  Most of them are
small and obvious.

The ipw2200 one [1] is big, but a lot of it is moving and/or deleting some
old code.  It fixes a problem that can cause a new scan request to
eclipse and existing one in a way that keeps userland from getting the
requested scan results.

Please let me know if there are problems!

Thanks,

John

[1] This one was also originally in a pending wireless-next-2.6 request.
I'm reformulating that request and will resend it.
