When setting rxon chain and filter, no need to commit RXON when the
chain flag is not changed. This reduces the number of RXON commands
we send down to uCode.

RXON command without association bit can clear the QoS info in the

Instead of unconditionally sending unassoc RXON,
before any assoc RXON, re-send only the AP STA
entry which is required after the BSSID has been
programmed into the device to set up internal
filters in the microcode properly.
This fixes some issues that we correlated with
sending a lot of RXON commands to the device.

Currently, when a PAN queue needs to be
stopped, we erroneously stop queue number 5
(for example) with mac80211 -- which doesn't
even exist!
To avoid that problem, recalculate the swq_id
for all queues when setting up the queues,
and don't use the default identity mapping
that is acceptable for devices which don't
support PAN.

Previously, we used the swq_id's mechanism
to have AC and HW queue different only for
aggregation queues. To be able to fix a bug
with iPAN simply always build the swq_id as
ac | (hwq << 2) and remove the flag bit.

Instead of passing the txq->swq_id, pass the

This patch move RX queue allocation to alloc_netdev_mq and freeing of
the queues to free_netdev (symmetric to TX queue allocation). Each
kobject RX queue takes a reference to the queue's device so that the
device can't be freed before all the kobjects have been released-- this
obviates the need for reference counts specific to RX queues.
