Like RTAX_ADVMSS, make the default calculation go through a dst_ops
method rather than caching the computation in the routing cache
entries.
Now dst metrics are pretty much left as-is when new entries are
created, thus optimizing metric sharing becomes a real possibility.

The current EEPROM reading code has some layout
assumptions that now turned out to be false with
some newer versions of the EEPROM. Luckily, we
can avoid all such assumptions by using data in
the EEPROM itself, so implement using that.
However, for risk mitigation purposes, keep the
old reading code for current hardware for now.

Make all RTAX_ADVMSS metric accesses go through a new helper function,
dst_metric_advmss().
Leave the actual default metric as "zero" in the real metric slot,
and compute the actual default value dynamically via a new dst_ops
AF specific callback.
For stacked IPSEC routes, we use the advmss of the path which
preserves existing behavior.
Unlike ipv4/ipv6, DecNET ties the advmss to the mtu and thus updates
advmss on pmtu updates. This inconsistency in advmss handling
results in more raw metric accesses than I wish we ended up with.

The Queue names were incorrectly copied from the legacy drivers,
as a result the queue names were inversed to what was expected.
This renames the queues using this mapping:
QID_AC_BK -> QID_AC_VO (priority 0)
QID_AC_BE -> QID_AC_VI (priority 1)
QID_AC_VI -> QID_AC_BE (priority 2)
QID_AC_VO -> QID_AC_BK (priority 3)
Note that this was a naming problem only, which didn't affect
the assignment of frames to their respective queues.

As part of the queue refactoring, change the queue callback
function names to have 3 different actions: start, kick & stop.
We can now also remove the STATE_RADIO_RX_ON/STATE_RADIO_RX_OFF
device_state flags, and replace the usage with using the
start_queue/stop_queue callback functions.
This streamlines the RX queue handling to the
similar approach as all other queues.

As part of the queue refactoring, we now introduce
3 queue commands: start, kick, stop.
- Start: will enable a queue, for TX this will
not mean anything, while for beacons and RX
this will update the registers to enable the queue.
- Kick: This will kick all pending frames to
the hardware. This is needed for the TX queue
to push all frames to the HW after the queue
has been started
- Stop: This will stop the queue in the hardware,
and cancel any pending work (So this doesn't
mean the queue is empty after a stop!).
Move all code from the drivers into the appropriate
functions, and link those calls to the old rt2x00lib
callback functions (we will fix this later when we
refactor the queue control inside rt2x00lib).
