    pjproject: ignore down interfaces · 9a5b8f3f
    Sébastien Blin authored
    Some interfaces (typically from docker or virtual machines) were added
    in the candidates even if down. For example:
    9: br-b8251442502e: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue
    state DOWN group default
    Even if state=DOWN if_enum_by_af consider the ip as valid and adds it in the
    candidates because IFF_UP is true. However, if_enum_by_af should use IFF_RUNNING
    to detect if the interface is up and running before adding it. Like
     iproute2/bridge/link.c does for print_link_flags.
