In kernel config files, it is supposed to be 'options<space><tab>' not
'options<tab><tab>', per long standing (but recently not so strictly
enforced) convention.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

Modify the routerstation config to use ukswitch for now.

Until an ADM6996 driver shows up, this allows for the two switch
ports to be used.

Oops - this was referencing a local file, which I've done away with.

Break out the AR71XX config file into _BASE and board specific
bits.

The ROUERSTATION and RSPRO variants contain:

* the board specific bits (eg the RTC for RSPRO, later on it'll
include the GPIO/LED definitions);
* the boot specific bits (eg, on-board flash, usb flash, etc).

For now the AR71XX_BASE file contains the common board config,
drivers and net80211/ath wireless drivers.

I'll follow this up with config files for the other boards I
have (eg the Ubiquiti LSSR71, as well as some Mikrotik boards
that use the AR71XX and atheros reference boards) which will
be quite easy to do now.
