    ipv6: add support of peer address · caeaba79
    Nicolas Dichtel authored
    This patch adds the support of peer address for IPv6. For example, it is
    possible to specify the remote end of a 6inY tunnel.
    This was already possible in IPv4:
     ip addr add ip1 peer ip2 dev dev1
    
    The peer address is specified with IFA_ADDRESS and the local address with
    IFA_LOCAL (like explained in include/uapi/linux/if_addr.h).
    Note that the API is not changed, because before this patch, it was not
    possible to specify two different addresses in IFA_LOCAL and IFA_REMOTE.
    There is a small change for the dump: if the peer is different from ::,
    IFA_ADDRESS will contain the peer address instead of the local address.
