Elsukov <ae@FreeBSD.org> CommitDate: 2025-10-26 11:21:14 +0000 arp: fix adding proxy entries for P2P interfaces The old rtsock implementation used in-kernel workaround to do so. When route to specified destination address used P2P interface, the kernel did the search with ifa_ifwithnet() for most suitable network and then add proxy entry to this interface. Use similar approach with netlink implementation. We already have get_ether_addr() function that does almost the same thing as ifa_ifwithnet(). Use it when we find that destination route uses P2P interface and then try to guess suitable interface. This should fix the use of netlink-based arp(8) in mpd5. Rename get_ether_addr() to get_ifinfo(), since now it is used to find only ifindex in case when hwaddr is specified by user. Also make set_nl() and delete_nl() prototype similar to rtsock. And allow '-i' to be used with '-S', since we already allow the same for '-s'.
