Subject: [PATCH v2] PS3: gelic: Add wireless support for PS3

Hi

PS3: gelic: Add wireless support for PS3

This is the version 2 of the re-worked (rewritten) version of the
wireless support driver for PS3. The version 1 of the new driver was
submitted on 13th Dec. 2007 (and the old one was submitted to net-dev ML
in June 2007).

Major differences with the old driver are:
- The new driver has a separate ethX interface from ethernet.
They share the same MAC address.
- Thus we can use both ethernet and wireless simultaenously.
- The new driver returns AP's cipher information by the common IE
format in the scan information.
- Cipher selection is done via the common wireless extension way

V2 changes:
- Emit more null IWAP events at appropriate timings, as Dan Williams
pointed out at the V1 submission.
- Fix sparse warnings
o make some functions as static
o use NULL for pointer instead of 0
- Remove extra space
