Subject: [PATCH AUTOSEL 4.9 11/12] net: ptp: add a definition for the UDP port for IEEE 1588 general messages

From: Vladimir Oltean <vladimir.oltean@....com>

[ 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
destination port assigned by IANA is 319 for event messages, and 320 for
general messages. Yet the kernel seems to be missing the definition for
general messages. This patch adds it.
