Jan reported that his b43-based laptop hangs during suspend. The problem turned out to be mac80211 asking the driver to stop the hardware before removing interfaces, and interface removal caused b43 to touch the hardware (while down, which causes the hang). This patch fixes mac80211 to do reorder these operations to have them in the correct order -- first remove interfaces and then stop the hardware. Some more code is necessary to be able to do so in a race-free manner, in particular it is necessary to not process frames received during quiescing.
