13 years agowl12xx: Cleanup PLT mode when module is removed
Juuso Oikarinen [Fri, 14 Jan 2011 11:48:46 +0000 (12:48 +0100)]
wl12xx: Cleanup PLT mode when module is removed

PLT mode start/stop is controlled from userspace. When removing module, the
PLT mode state is however not checked, and not cleared. There is the possibility
of some unwanted state to left linger and there is even the possiblity of a
kernel crash if for instance IRQ work is running when the module is removed.

Fix this by stopping PLT mode on module removal, if still running.

Since baseband hangs are rare, but the hang check function has a high
false positive rate in some situations, we need to add more reliable

In AP mode we can use blocked beacon transmissions as an indicator,

In station mode, we can skip the hang check entirely, since a true
hang will trigger beacon loss detection, and mac80211 will rescan,
which leads to a hw reset that will bring the hardware back to life.
