Subject: [PATCH v1 4/4] staging: r8188eu: use htons macro instead of
 __constant_htons

Macro "htons" is more efficient and clearer. It should be used for
constants instead of the __contast_htons macro. Resolves following
checkpatch script complaint:
        WARNING: __constant_htons should be htons

Signed-off-by: Deepak R Varma <drv@...lo.com>
