Merge branch 'af-xdp-sock-diag'
Björn Töpel says:
====================
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.
v1->v2:
* Removed extra newline
* Zero-out all user-space facing structures prior setting the
members
* Added explicit "pad" member in _msg struct
* Removed unused variable "req" in xsk_diag_handler_dump()
Thanks to Daniel for reviewing the series!
