With the original code, GCC + sparse emit a dozen of warnings like the 
following ones:

drivers/staging/r8188eu/core/rtw_br_ext.c:693:101: warning: incorrect type in 
argument 2 (different base types)
drivers/staging/r8188eu/core/rtw_br_ext.c:693:101:    expected unsigned int 
*ipxNetAddr
drivers/staging/r8188eu/core/rtw_br_ext.c:693:101:    got restricted __be32 *
drivers/staging/r8188eu/core/rtw_br_ext.c:693:123: warning: incorrect type in 
argument 3 (different base types)
drivers/staging/r8188eu/core/rtw_br_ext.c:693:123:    expected unsigned short

drivers/staging/r8188eu/core/rtw_br_ext.c:693:123:    got restricted __be16 *
drivers/staging/r8188eu/core/rtw_br_ext.c:698:99: warning: incorrect type in 
argument 2 (different base types)

Do we want the above pasted warnings and leave the code as-is?
