/* PFLINUX: <net/if.h> — glibc's <net/if.h> plus OpenBSD's interface-group
 * ABI (sys/sockio.h) used by pfctl_parser.c (ifa_exists/ifa_grouplookup).
 * Linux has no interface groups: SIOCGIFGMEMB keeps the OpenBSD encoding
 * (it is computed with our OpenBSD _IOWR) and every use of it on an AF_INET
 * socket returns ENOTTY, so group lookups degrade to "not a group" exactly
 * like on an OpenBSD without the group. */
