    Babel: Add support for dual-stack IPv4/IPv6 operation · 4324025f

    This adds support for dual-stack v4/v6 operation to the Babel protocol.
    Routing messages will be exchanged over IPv6, but IPv4 routes can be
    carried in the messages being exchanged. This matches how the reference
    Babel implementation (babeld) works.
    
    The nexthop address for v4 can be configured per interface, and will
    default to the first available IPv4 address on the given interface. For
    symmetry, a configuration option to configure the IPv6 nexthop address
    is also added.
    
    Thanks to Toke Høiland-Jørgensen <toke@toke.dk> for the patch.
