+ * set these flags using userspace utilities but there is also a sysfs
+ * entry available for all dev flags which can be queried and set. These flags
+ * are shared for all types of net_devices. The sysfs entries are available
+ * via /sys/class/net/<dev>/flags. Flags which can be toggled through sysfs
+ * are annotated below, note that only a few flags can be toggled and some
+ * other flags are always preserved from the original net_device flags
+ * even if you try to set them via sysfs. Flags which are always preserved
+ * are kept under the flag grouping @IFF_VOLATILE. Flags which are volatile
+ * are annotated below as such.
+ *
+ * You should have a pretty good reason to be extending these flags.
+ *
+ * @IFF_UP: interface is up. Can be toggled through sysfs.
+ * @IFF_BROADCAST: broadcast address valid. Volatile.

+ * @IFF_NOARP: no ARP protocol. Can be toggled through sysfs. Volatile.
+ * @IFF_PROMISC: receive all packets. Can be toggled through sysfs.
+ * @IFF_ALLMULTI: receive all multicast packets. Can be toggled through

+ * @IFF_MASTER: master of a load balancer. Volatile.
+ * @IFF_SLAVE: slave of a load balancer. Volatile.
+ * @IFF_MULTICAST: Supports multicast. Can be toggled through sysfs.
+ * @IFF_PORTSEL: can set media type. Can be toggled through sysfs.

+ * Compatibility interface for userspace libc header coordination:
+ *
+ * Define compatibility macros that are used to control the inclusion or
+ * exclusion of UAPI structures and definitions in coordination with another
+ * userspace C library.
+ *
+ * This header is intended to solve the problem of UAPI definitions that
+ * conflict with userspace definitions. If a UAPI header has such conflicting
+ * definitions then the solution is as follows:
+ *
+ * * Synchronize the UAPI header and the libc headers so either one can be
+ *   used and such that the ABI is preserved. If this is not possible then
+ *   no simple compatibility interface exists (you need to write translating
+ *   wrappers and rename things) and you can't use this interface.
+ *
+ * Then follow this process:
+ *
+ * (a) Include libc-compat.h in the UAPI header.
+ *      e.g. #include <linux/libc-compat.h>
+ *     This include must be as early as possible.
+ *
+ * (b) In libc-compat.h add enough code to detect that the comflicting
+ *     userspace libc header has been included first.
+ *
+ * (c) If the userspace libc header has been included first define a set of
+ *     guard macros of the form __UAPI_DEF_FOO and set their values to 1, else
+ *     set their values to 0.
+ *
+ * (d) Back in the UAPI header with the conflicting definitions, guard the
+ *     definitions with:
+ *     #if __UAPI_DEF_FOO
+ *       ...
+ *     #endif
+ *
+ * This fixes the situation where the linux headers are included *after* the
+ * libc headers. To fix the problem with the inclusion in the other order the
+ * userspace libc headers must be fixed like this:
+ *
+ * * For all definitions that conflict with kernel definitions wrap those
+ *   defines in the following:
+ *   #if !__UAPI_DEF_FOO
+ *     ...
+ *   #endif
+ *
+ * This prevents the redefinition of a construct already defined by the kernel.

+ * =============
+ *
+ * The below enums and macros are for interfacing with WireGuard, using generic
+ * netlink, with family WG_GENL_NAME and version WG_GENL_VERSION. It defines two
+ * methods: get and set. Note that while they share many common attributes,
+ * these two functions actually accept a slightly different set of inputs and
+ * outputs.
+ *
+ * WG_CMD_GET_DEVICE
+ * -----------------
+ *
+ * May only be called via NLM_F_REQUEST | NLM_F_DUMP. The command should contain
+ * one but not both of:
+ *
+ *    WGDEVICE_A_IFINDEX: NLA_U32
+ *    WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMSIZ - 1
+ *
+ * The kernel will then return several messages (NLM_F_MULTI) containing the
+ * following tree of nested items:
+ *
+ *    WGDEVICE_A_IFINDEX: NLA_U32
+ *    WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMSIZ - 1
+ *    WGDEVICE_A_PRIVATE_KEY: NLA_EXACT_LEN, len WG_KEY_LEN
+ *    WGDEVICE_A_PUBLIC_KEY: NLA_EXACT_LEN, len WG_KEY_LEN
+ *    WGDEVICE_A_LISTEN_PORT: NLA_U16
+ *    WGDEVICE_A_FWMARK: NLA_U32
+ *    WGDEVICE_A_PEERS: NLA_NESTED
+ *        0: NLA_NESTED
+ *            WGPEER_A_PUBLIC_KEY: NLA_EXACT_LEN, len WG_KEY_LEN
+ *            WGPEER_A_PRESHARED_KEY: NLA_EXACT_LEN, len WG_KEY_LEN
+ *            WGPEER_A_ENDPOINT: NLA_MIN_LEN(struct sockaddr), struct sockaddr_in or struct sockaddr_in6
+ *            WGPEER_A_PERSISTENT_KEEPALIVE_INTERVAL: NLA_U16
+ *            WGPEER_A_LAST_HANDSHAKE_TIME: NLA_EXACT_LEN, struct __kernel_timespec
+ *            WGPEER_A_RX_BYTES: NLA_U64
+ *            WGPEER_A_TX_BYTES: NLA_U64
+ *            WGPEER_A_ALLOWEDIPS: NLA_NESTED
+ *                0: NLA_NESTED
+ *                    WGALLOWEDIP_A_FAMILY: NLA_U16
+ *                    WGALLOWEDIP_A_IPADDR: NLA_MIN_LEN(struct in_addr), struct in_addr or struct in6_addr
+ *                    WGALLOWEDIP_A_CIDR_MASK: NLA_U8
+ *                0: NLA_NESTED
+ *                    ...
+ *                0: NLA_NESTED
+ *                    ...
+ *                ...
+ *            WGPEER_A_PROTOCOL_VERSION: NLA_U32
+ *        0: NLA_NESTED
+ *            ...
+ *        ...
+ *
+ * It is possible that all of the allowed IPs of a single peer will not
+ * fit within a single netlink message. In that case, the same peer will
+ * be written in the following message, except it will only contain
+ * WGPEER_A_PUBLIC_KEY and WGPEER_A_ALLOWEDIPS. This may occur several
+ * times in a row for the same peer. It is then up to the receiver to
+ * coalesce adjacent peers. Likewise, it is possible that all peers will
+ * not fit within a single message. So, subsequent peers will be sent
+ * in following messages, except those will only contain WGDEVICE_A_IFNAME
+ * and WGDEVICE_A_PEERS. It is then up to the receiver to coalesce these
+ * messages to form the complete list of peers.
+ *
+ * Since this is an NLA_F_DUMP command, the final message will always be
+ * NLMSG_DONE, even if an error occurs. However, this NLMSG_DONE message
+ * contains an integer error code. It is either zero or a negative error
+ * code corresponding to the errno.
+ *
+ * WG_CMD_SET_DEVICE
+ * -----------------
+ *
+ * May only be called via NLM_F_REQUEST. The command should contain the
+ * following tree of nested items, containing one but not both of
+ * WGDEVICE_A_IFINDEX and WGDEVICE_A_IFNAME:
+ *
+ *    WGDEVICE_A_IFINDEX: NLA_U32
+ *    WGDEVICE_A_IFNAME: NLA_NUL_STRING, maxlen IFNAMSIZ - 1
+ *    WGDEVICE_A_FLAGS: NLA_U32, 0 or WGDEVICE_F_REPLACE_PEERS if all current
+ *                      peers should be removed prior to adding the list below.
+ *    WGDEVICE_A_PRIVATE_KEY: len WG_KEY_LEN, all zeros to remove
+ *    WGDEVICE_A_LISTEN_PORT: NLA_U16, 0 to choose randomly
+ *    WGDEVICE_A_FWMARK: NLA_U32, 0 to disable
+ *    WGDEVICE_A_PEERS: NLA_NESTED
+ *        0: NLA_NESTED
+ *            WGPEER_A_PUBLIC_KEY: len WG_KEY_LEN
+ *            WGPEER_A_FLAGS: NLA_U32, 0 and/or WGPEER_F_REMOVE_ME if the
+ *                            specified peer should not exist at the end of the
+ *                            operation, rather than added/updated and/or
+ *                            WGPEER_F_REPLACE_ALLOWEDIPS if all current allowed
+ *                            IPs of this peer should be removed prior to adding
+ *                            the list below and/or WGPEER_F_UPDATE_ONLY if the
+ *                            peer should only be set if it already exists.
+ *            WGPEER_A_PRESHARED_KEY: len WG_KEY_LEN, all zeros to remove
+ *            WGPEER_A_ENDPOINT: struct sockaddr_in or struct sockaddr_in6
+ *            WGPEER_A_PERSISTENT_KEEPALIVE_INTERVAL: NLA_U16, 0 to disable

+ *                                       most recent protocol will be used when
+ *                                       this is unset. Otherwise, must be set
+ *                                       to 1.
+ *        0: NLA_NESTED
+ *            ...
+ *        ...
+ *
+ * It is possible that the amount of configuration data exceeds that of
+ * the maximum message length accepted by the kernel. In that case, several
+ * messages should be sent one after another, with each successive one
+ * filling in information not contained in the prior. Note that if
+ * WGDEVICE_F_REPLACE_PEERS is specified in the first message, it probably
+ * should not be specified in fragments that come after, so that the list
+ * of peers is only cleared the first time but appended after. Likewise for
+ * peers, if WGPEER_F_REPLACE_ALLOWEDIPS is specified in the first message
+ * of a peer, it likely should not be specified in subsequent fragments.
+ *
+ * If an error occurs, NLMSG_ERROR will reply containing an errno.
