rGf7937053fd08: arp: fix adding proxy entries for P2P interfaces
rG9e829d0693a7: arp: fix adding proxy entries for P2P interfaces
rGc26d6bf9da01: arp: fix adding proxy entries for P2P interfaces
Summary
  • rename get_ether_addr into get_ifinfo and teach it to return if_index and if_flags for found interface.
  • allow '-S' to be used with '-i'
  • rework guess_ifindex to do proxy interface automatic detection for IFF_POINTOPOINT interface in a similar way as it is done in kernel with rtsock.
