From: Jérôme Pouiller <jerome.pouil...@silabs.com>
The structure hif_mib_set_association_mode come from hardware API. It is
not intended to be manipulated in upper layers of the driver.
In add, current code for hif_set_association_mode() is too dumb. It
should pack data with hardware representation instead of leaving all
work to the caller.
