805  * The PCU lock is non-recursive and should be treated as a spinlock.
806  * Although currently the interrupt code is run in netisr context and

808  * Please keep this in mind when protecting certain code paths
809  * with the PCU lock.
810  *
811  * The PCU lock is used to serialise access to the PCU so things such
812  * as TX, RX, state change (eg channel change), channel reset and updates
813  * from interrupt context (eg kickpcu, txqactive bits) do not clash.
814  *
815  * Although the current single-thread taskqueue mechanism protects the
816  * majority of these situations by simply serialising them, there are
817  * a few others which occur at the same time. These include the TX path
818  * (which only acquires ATH_LOCK when recycling buffers to the free list),
819  * ath_set_channel, the channel scanning API and perhaps quite a bit more.
