From: Jérôme Pouiller <jerome.pouil...@silabs.com>
The structure hif_mib_arp_ip_addr_table come from hardware API. It is
not intended to be manipulated in upper layers of the driver.
In add, current code for hif_set_arp_ipv4_filter() is too dumb. It
should pack data using the hardware representation instead of leaving
all work to the caller.
