I added a feature to my tree that makes it possible to
conveniently inject a simulated TX queue overflow every
second. This could be used to test code in the stack
that's handling this rare event that almost never happens
in the real world (with sane hardware, at least :) )

You need to compile bcm43xx-mac80211 with debugging support.
The injection is enabled at runtime through debugfs
by doing:
echo 1 >/debug/bcm43xx_mac80211/phyX/debug_dmaoverflow
It prints a debugging message to dmesg every time it
injects a fault.
