SubjectRe: [PATCH AUTOSEL 4.4 8/9] net: ptp: add a definition for the UDP port for IEEE 1588 general messages

> [ Upstream commit ec15baec3272bbec576f2ce7ce47765a8e9b7b1c ]
> As opposed to event messages (Sync, PdelayReq etc) which require
> timestamping, general messages (Announce, FollowUp etc) do not.
> In PTP they are part of different streams of data.
> IEEE 1588-2008 Annex D.2 "UDP port numbers" states that the UDP

This does not fix any bug in 4.4, right? We do not need it in stable.
