ar71xx: Buffalo WLAE-AG300N initial support
The patch set for Buffalo WLAE-AG300N initial support. There is another patch for wireless led support that is posted separately. Note on serial console: This unit has buffalo standard 4 pin console, but the unit may not power on if some console apparatus is connected. This is probably due to some electronic interaction between the unit's electronic power switch circuit and the serial console apparatus. If this happens, it is required to power on the unit without the console, then quickly (re-)attach it.
