Subject: [net-next 02/14] ice: support adding 16 unicast/multicast filter on untrusted VF

From: Paul Greenwalt <paul.greenwalt@...el.com>

Allow untrusted VF to add 16 unicast/multicast filters. VF uses 1 filter
for the default/perm_addr/LAA MAC, 1 for broadcast, and 16 additional
unicast/multicast filters.
