I've mentioned this before..but I have a patch that works around this

I had merge issues, so now it's two patches until I have time to clean up
my tree:



I suspect this may cause memory leaks, as a test that causes these work-arounds to hit
often will run out of memory after a few days (200+ station vifs constantly doing traffic).
Could be lots of other code of course, and kmemleak shows no leaks, so I'm at a loss on
the mem leak issue.

If you can, try patching these in and see if that works around your tx hang problem.

I'd love to have a better fix, btw.
