Questions on libertas driver

[Cyril HAENEL]

In fact I modified ALL le16_to_cpu() function calls to implement the 
get_unaligned((u16*), to be sure !!

Instead of use get_unaligned, which surely eat cpu time, it cannot be 
possible to directly align data used by the driver ? In structure and 
other ?
Or maybe it exists an option in the blackfin gcc to do this automaticaly 
at compilation ?
