This patch contains following modifications:

- Add mesh capabilities on fw.c to permit creation of mesh
  interfaces using this driver.

- Modify carl9170_set_operating_mode, to use AP-style beaconing
  with mesh interfaces.

- Allow beacon updates for NL80211_IFTYPE_MESH_POINT type in
  carl9170_handle_command_response.

- Add NL80211_IFTYPE_MESH_POINT case on carl9170_op_add_interfaces to
  support mesh/ap/sta virtual interface combinations.

First of all, use PHY names instead of magic numbers. It should make
configuring kernel easier in case of not enabled PHY type support.
Secondly, always print info about PHY. This is really basic info about
hardware and quite important for the support level.

Drivers that load firmware from their probe routine have problems with the
latest versions of udev as they get timeouts while waiting for user
space to start. The problem is fixed by using request_firmware_nowait()
and delaying the start of mac80211 until the firmware is loaded.

To prevent the possibility of the driver being unloaded while the firmware
loading callback is still active, a completion queue entry is used.

We need to wait for the command completion event when we send the
CMD_ROLE_STOP event otherwise we may try to send CMD_ROLE_START too
soon and get out-of-sync with the firmware.

In some cases, the firmware may not send the event, so we wait for the
event or for the timeout, whichever comes first.

This patch is based on an earlier version by Eliad.

this completes the calibrator based fem detect logic in driver:
driver starts (by calibrator) in plt_mode PLT_FEM_DETECT
wlcore inits and starts plt on wl12xx
wl12xx fetches fem number from firmware and stores it in wl->fem_manuf
wl12xx immediatly returns (doesn't start radio, etc...)

it changes the number of queues at runtime which,
while it was never really supported, now crashes
mac80211 due to the new hardware queue logic.

earlier and registering with mac80211 with the
right number of queues.
