linux-cp: update adjs for subifs too when mac changes
The plugin creates and manages adjacencies for the physical interface in each interface pair (they are part of the x-connect feature). When a link update notification is received from the host system, MAC address of the corresponding physical interface is updated (as needed) as well as previously created adjacencies for it (because a new rewrite string needs to be generated). Subinterfaces inherit MAC address from the parent interface. When MAC address of the parent interface changes, it also implies MAC address change for its subinterfaces. The problem is that this is currently not considered in the plugin. After MAC address update on the parent interface, packets sent from subinterfaces might have wrong source MAC address. For example, IPv6 Neighbor Solicitation messages will be sent with the wrong (previous) MAC address and neighbor discovery will fail. With this fix, when the plugin updates adjacencies for a physical interface, it will also update adjacencies for the subinterfaces with existing interface pair.
