Rajkumar Manoharan 693828fe92 mac80211: stop tx before doing hw config and rate update
The assumption is that during the hw config, transmission was
already stopped by mac80211. Sometimes the AP can be switching
b/w the ht modes due to intolerant or etc where STA is in
the middle of transmission. In such scenario, buffer overflow
was observed at driver side. And also before updating the rate
control, the frames are continued to xmited with older rates.
This patch ensures that the frames are always xmitted with
updated rates and avoid buffer overflow.

Javier Cardona cfee66b0f9 mac80211: Stop forwarding mesh traffic when tx queues are full
Tx flow control for non-mesh modes of operation only needs to act on the
net device queues: when the hardware queues are full we stop accepting
traffic from the net device.  In mesh, however, we also need to stop
forwarding traffic.  This patch checks the hardware queues before
attempting to forward a mesh frame.

Sven Neumann eac03e3819 cfg80211: hold reg_mutex when updating regulatory
The function wiphy_update_regulatory() uses the static variable
last_request and thus needs to be called with reg_mutex held.
This is the case for all users in reg.c, but the function was
exported for use by wiphy_register(), from where it is called
without the lock being held.

Fix this by making wiphy_update_regulatory() private and introducing
regulatory_update() as a wrapper that acquires and holds the lock.

The firmware only asks for one dummy packet at a time, but sometimes we
are unable to provide it before a FW timer expires. When this happens,
the FW will re-request the dummy packet. If a packet is still queued in
the driver queues, do nothing in this case.

This prevents spurious dummy packets from clogging up the VO AC.
