It is not clear why you set cc.mult in a different place than
cc.shift. That isn't logical, but maybe later patches make it
clear...
cc.mult has to be reloaded to original value each time CPTS is registered(restarted)
as it can be modified by cpts_ptp_adjfreq().
While cc.shift is static.
Will it ok if i will add comment here and re-send series?
