+Libbpf
+======
+
+Libbpf is a helper library for eBPF and XDP that makes using these
+technologies a lot simpler. It also contains specific helper functions
+in tools/lib/bpf/xsk.h for facilitating the use of AF_XDP. It
+contains two types of functions: those that can be used to make the

+plane operations.

+Configuration Flags and Socket Options
+======================================
+
+These are the various configuration flags that can be used to control
+and monitor the behavior of AF_XDP sockets.
+
+XDP_COPY and XDP_ZERO_COPY bind flags
+-------------------------------------
+
+When you bind to a socket, the kernel will first try to use zero-copy
+copy. If zero-copy is not supported, it will fall back on using copy
+mode, i.e. copying all packets out to user space. But if you would
+like to force a certain mode, you can use the following flags. If you
+pass the XDP_COPY flag to the bind call, the kernel will force the
+socket into copy mode. If it cannot use copy mode, the bind call will
+fail with an error. Conversely, the XDP_ZERO_COPY flag will force the
+socket into zero-copy mode or fail.
+
+XDP_SHARED_UMEM bind flag
+-------------------------
+
+This flag enables you to bind multiple sockets to the same UMEM, but
+only if they share the same queue id. In this mode, each socket has
+their own RX and TX rings, but the UMEM (tied to the fist socket
+created) only has a single FILL ring and a single COMPLETION
+ring. To use this mode, create the first socket and bind it in the normal
+way. Create a second socket and create an RX and a TX ring, or at
+least one of them, but no FILL or COMPLETION rings as the ones from
+the first socket will be used. In the bind call, set he
+XDP_SHARED_UMEM option and provide the initial socket's fd in the
+sxdp_shared_umem_fd field. You can attach an arbitrary number of extra
+sockets this way.
+
+What socket will then a packet arrive on? This is decided by the XDP
+program. Put all the sockets in the XSK_MAP and just indicate which
+index in the array you would like to send each packet to. A simple
+round-robin example of distributing packets is shown below:
+
+.. code-block:: c
+
+   #include <linux/bpf.h>
+   #include "bpf_helpers.h"
+
+   #define MAX_SOCKS 16
+
+   struct {
+        __uint(type, BPF_MAP_TYPE_XSKMAP);
+        __uint(max_entries, MAX_SOCKS);
+        __uint(key_size, sizeof(int));
+        __uint(value_size, sizeof(int));
+   } xsks_map SEC(".maps");
+
+   static unsigned int rr;
+
+   SEC("xdp_sock") int xdp_sock_prog(struct xdp_md *ctx)
+   {
+	rr = (rr + 1) & (MAX_SOCKS - 1);
+
+	return bpf_redirect_map(&xsks_map, rr, 0);
+   }
+
+Note, that since there is only a single set of FILL and COMPLETION
+rings, and they are single producer, single consumer rings, you need
+to make sure that multiple processes or threads do not use these rings
+concurrently. There are no synchronization primitives in the
+libbpf code that protects multiple users at this point in time.
+
+XDP_USE_NEED_WAKEUP bind flag
+-----------------------------
+
+This option adds support for a new flag called need_wakeup that is
+present in the FILL ring and the TX ring, the rings for which user
+space is a producer. When this option is set in the bind call, the
+need_wakeup flag will be set if the kernel needs to be explicitly
+woken up by a syscall to continue processing packets. If the flag is
+zero, no syscall is needed.
+
+If the flag is set on the FILL ring, the application needs to call
+poll() to be able to continue to receive packets on the RX ring. This
+can happen, for example, when the kernel has detected that there are no
+more buffers on the FILL ring and no buffers left on the RX HW ring of
+the NIC. In this case, interrupts are turned off as the NIC cannot
+receive any packets (as there are no buffers to put them in), and the
+need_wakeup flag is set so that user space can put buffers on the
+FILL ring and then call poll() so that the kernel driver can put these
+buffers on the HW ring and start to receive packets.
+
+If the flag is set for the TX ring, it means that the application
+needs to explicitly notify the kernel to send any packets put on the
+TX ring. This can be accomplished either by a poll() call, as in the
+RX path, or by calling sendto().
+
+An example of how to use this flag can be found in
+samples/bpf/xdpsock_user.c. An example with the use of libbpf helpers
+would look like this for the TX path:
+
+.. code-block:: c
+
+   if (xsk_ring_prod__needs_wakeup(&my_tx_ring))
+      sendto(xsk_socket__fd(xsk_handle), NULL, 0, MSG_DONTWAIT, NULL, 0);
+
+I.e., only use the syscall if the flag is set.
+
+We recommend that you always enable this mode as it usually leads to
+better performance especially if you run the application and the
+driver on the same core, but also if you use different cores for the
+application and the kernel driver, as it reduces the number of
+syscalls needed for the TX path.
+
+XDP_{RX|TX|UMEM_FILL|UMEM_COMPLETION}_RING setsockopts
+------------------------------------------------------
+
+These setsockopts sets the number of descriptors that the RX, TX,
+FILL, and COMPLETION rings respectively should have. It is mandatory
+to set the size of at least one of the RX and TX rings. If you set
+both, you will be able to both receive and send traffic from your
+application, but if you only want to do one of them, you can save
+resources by only setting up one of them. Both the FILL ring and the
+COMPLETION ring are mandatory if you have a UMEM tied to your socket,
+which is the normal case. But if the XDP_SHARED_UMEM flag is used, any
+socket after the first one does not have a UMEM and should in that
+case not have any FILL or COMPLETION rings created.
+
+XDP_UMEM_REG setsockopt
+-----------------------
+
+This setsockopt registers a UMEM to a socket. This is the area that
+contain all the buffers that packet can recide in. The call takes a
+pointer to the beginning of this area and the size of it. Moreover, it
+also has parameter called chunk_size that is the size that the UMEM is
+divided into. It can only be 2K or 4K at the moment. If you have an
+UMEM area that is 128K and a chunk size of 2K, this means that you
+will be able to hold a maximum of 128K / 2K = 64 packets in your UMEM
+area and that your largest packet size can be 2K.
+
+There is also an option to set the headroom of each single buffer in
+the UMEM. If you set this to N bytes, it means that the packet will
+start N bytes into the buffer leaving the first N bytes for the
+application to use. The final option is the flags field, but it will
+be dealt with in separate sections for each UMEM flag.
+
+SO_BINDTODEVICE setsockopt
+--------------------------
+
+This is a generic SOL_SOCKET option that can be used to tie AF_XDP
+socket to a particular network interface.  It is useful when a socket
+is created by a privileged process and passed to a non-privileged one.
+Once the option is set, kernel will refuse attempts to bind that socket
+to a different interface.  Updating the value requires CAP_NET_RAW.
+
+XDP_STATISTICS getsockopt
+-------------------------
+
+Gets drop statistics of a socket that can be useful for debug
+purposes. The supported statistics are shown below:
+
+.. code-block:: c
+
+   struct xdp_statistics {
+	  __u64 rx_dropped; /* Dropped for reasons other than invalid desc */
+	  __u64 rx_invalid_descs; /* Dropped due to invalid descriptor */
+	  __u64 tx_invalid_descs; /* Dropped due to invalid descriptor */
+   };
+
+XDP_OPTIONS getsockopt
+----------------------
+
+Gets options from an XDP socket. The only one supported so far is
+XDP_OPTIONS_ZEROCOPY which tells you if zero-copy is on or not.
