Sorry for taking a slight aside here. Does that also mean that 7.4 is
going to ship with the necessary kernel changes backported to allow
hardware timestamping to work?
I have played around with chrony 3.1 on both CentOS 6.8 and CentOS 7.3
(built myself) and both were missing kernel features necessary to allow the
hardware timestamping to work (I believe in 6 it was lack of
`SO_SELECT_ERR_QUEUE' and `SOF_TIMESTAMPING_OPT_CMSG', but in 7 it was just
