Subject: NDA_PORT attribute is useless

I noticed that this commit is also broken.
Because although you can specify alternate UDP ports for sending,
it does nothing to enable those ports for reception. So although you
can create new static neighbour entries with different ports, they
are useless.

    vxlan: generalize forwarding tables
    
    This patch generalizes VXLAN forwarding table entries allowing an administra
    to:
        1) specify multiple destinations for a given MAC
        2) specify alternate vni's in the VXLAN header
        3) specify alternate destination UDP ports
        4) use multicast MAC addresses as fdb lookup keys
        5) specify multicast destinations
        6) specify the outgoing interface for forwarded packets
    
    The combination allows configuration of more complex topologies using VXLAN
    encapsulation.
    
    Changes since v1: rebase to 3.9.0-rc2
