179 For an example on how create AF_XDP sockets, please see the AF_XDP-example and
180 AF_XDP-forwarding programs in the `bpf-examples`_ directory in the `libxdp`_ repository.
181 For a detailed explanation of the AF_XDP interface please see:
184 - `AF_XDP`_ kernel documentation.
187 The most comprehensive resource for using XSKMAPs and AF_XDP is `libxdp`_.
