[v1] net: Implement missing SO_TIMESTAMPING_NEW cmsg support

[PATCH RESEND net] net: Implement missing SO_TIMESTAMPING_NEW cmsg support

Posted by Thomas Lange 1 year, 11 months ago

Commit 9718475e6908 ("socket: Add SO_TIMESTAMPING_NEW") added the new
socket option SO_TIMESTAMPING_NEW. However, it was never implemented in
__sock_cmsg_send thus breaking SO_TIMESTAMPING cmsg for platforms using
SO_TIMESTAMPING_NEW.

Fixes: 9718475e6908 ("socket: Add SO_TIMESTAMPING_NEW")
