/* PFLINUX: <net/if_dl.h> — BSD link-layer address.  Linux has no AF_LINK;
 * getifaddrs() reports link-layer addresses as AF_PACKET/struct sockaddr_ll.
 * We therefore define AF_LINK as AF_PACKET and lay struct sockaddr_dl out
 * exactly like struct sockaddr_ll, so pfctl_parser.c's
 * ((struct sockaddr_dl *)ifa->ifa_addr)->sdl_index finds sll_ifindex.
 * Everything stays userland-internal: af values tagged AF_LINK never cross
 * /dev/pf (rules carry ifname strings, not sockaddr families). */
