DefaultReadOnlyOpts provides recommended default options for initializing a readonly AF_XDP socket.

ReadOnlyFromSocket takes an AF_XDP socket, initializes it, and binds it to a particular interface and queue.

ReadOnlySocket returns an initialized read-only AF_XDP socket bound to a particular interface and queue.

The CompletionQueue is how the kernel tells a process which buffers have been transmitted and can be reused.

A ControlBlock contains all the control structures necessary to use an AF_XDP socket.

The FillQueue is how a process tells the kernel which buffers are available to be filled by incoming packets.

ReadOnlySocketOpts configure a read-only AF_XDP socket.

The RXQueue is how the kernel tells a process which buffers are full with incoming packets.

The TXQueue is how a process tells the kernel which buffers are available to be sent via the NIC.

UMEM is the shared memory area that the kernel and userspace put packets in.
