Subject[PATCH 07/31] staging: wfx: drop useless function
Date
From: Jérôme Pouiller <jerome.pouiller@silabs.com>

Since the code for multicast filtering has been dropped, the function
hif_set_data_filtering() is only called to disable multicast filtering.
In fact, the multicast filtering is already disabled by default. So,
this function is useless and can be dropped.
