ice: receive LLDP on trusted VFs

Browse source 
When a trusted VF tries to configure an LLDP multicast address, configure a
rule that would mirror the traffic to this VF, untrusted VFs are not
allowed to receive LLDP at all, so the request to add LLDP MAC address will
always fail for them.

Add a forwarding LLDP filter to a trusted VF when it tries to add an LLDP
multicast MAC address. The MAC address has to be added after enabling
trust (through restarting the LLDP service).
