2009-10-27wl1271: fix endianess issuesLuciano Coelho
We were not handling endianess correctly. The wl1271 chip runs on little-endian values. This patch makes sure that all the communication with the wl1271 firmware is done in little-endian by using cpu_to_le* and le*_to_cpu where appropriate. Also, all the struct definitions for data exchanged with the firmware has been changed to use __le16/32 types instead of u16/32.
