From: Björn Töpel <bjorn.to...@intel.com> This series adds an AF_XDP sock_diag interface for querying sockets from user-space. Tools like iproute2 ss(8) can use this interface to list open AF_XDP sockets.
The diagnostic provides information about the Rx/Tx/fill/completetion rings, umem, memory usage and such. For a complete list, please refer to the xsk_diag.c file. The AF_XDP sock_diag interface is optional, and can be built as a module. A separate patch series, adding ss(8) iproute2 support, will follow.
