Vadim Fedorenko suggested to add an alternative API for receiving
tx timestamps through io_uring. The series introduces io_uring socket
cmd for fetching tx timestamps, which is a polled multishot request,
i.e. internally polling the socket for POLLERR and posts timestamps
when they're arrives. For the API description see Patch 5.

It reuses existing timestamp infra and takes them from the socket's
error queue. For networking people the important parts are Patch 1,
and io_uring_cmd_timestamp() from Patch 5 walking the error queue.

[...]

Applied, thanks!
