qed*: Allow unicast filtering
Apparently qede fails to set IFF_UNICAST_FLT, and as a result is not
actually performing unicast MAC filtering.
While we're at it - relax a hard-coded limitation that limits each
interface into using at most 15 unicast MAC addresses before turning
promiscuous. Instead utilize the HW resources to their limit.
