From 4aecca4c76808f3736056d18ff510df80424bc9f Mon Sep 17 00:00:00 2001 From: Vadim Fedorenko Date: Tue, 1 Oct 2024 05:57:14 -0700 Subject: net_tstamp: add SCM_TS_OPT_ID to provide OPT_ID in control message SOF_TIMESTAMPING_OPT_ID socket option flag gives a way to correlate TX timestamps and packets sent via socket. Unfortunately, there is no way to reliably predict socket timestamp ID value in case of error returned by sendmsg. For UDP sockets it's impossible because of lockless nature of UDP transmit, several threads may send packets in parallel. In case of RAW sockets MSG_MORE option makes things complicated. More details are in the conversation [1]. This patch adds new control message type to give user-space software an opportunity to control the mapping between packets and values by providing ID with each sendmsg for UDP sockets. The documentation is also added in this patch.

There is no other maintainer and the driver is quite old. There is a good chance nobody is using this driver any more. Let's try to remove it completely, we can revert it back in if someone complains.
