This patch introduces two new MGMT events for notifying the bluetoothd
whenever the controller starts/stops monitoring a device.

Test performed:
- Verified by logs that the MSFT Monitor Device is received from the
  controller and the bluetoothd is notified whenever the controller
  starts/stops monitoring a device.

Whenever the controller starts/stops monitoring a bt device, it sends
MSFT Monitor Device event. Add handler to read this vendor event.

net: make dev_watchdog() less intrusive

dev_watchdog() is used on many NIC to periodically monitor TX queues
to detect hangs.

Problem is : It stops all queues, then check them, then 'unfreeze' them.

Not only this stops feeding the NIC, it also migrates all qdiscs
to be serviced on the cpu calling netif_tx_unlock(), causing
a potential latency artifact.

With many TX queues, this is becoming more visible.

tx_timeout_show() assumed dev_watchdog() would stop all
the queues, to fetch queue->trans_timeout under protection
of the queue->_xmit_lock.

As we want to no longer disrupt transmits, we use an
atomic_long_t instead.

If the used PHYs also support hardware timestamping, all configuration requests
should be forwared to the PHYs instead of being processed by the MAC driver
itself.

This enables PHY timestamping in combination with the cpsw driver.

Tested with an am335x based board with two DP83640 PHYs connected to the cpsw
switch.

Don't create eswitch QoS (root TSAR) on switch mode change. Create it on

No need to check for QoS is enabled when installing tc matchall filter.
