Add struct PortStats to keep per-port number of messages sent and received,
split by message type. Bump TX counters after messages are sent
successfully, and RX counters after a message is received. To keep things
simple, reserve one counter for each theoretically possible message type,
including
mc6_addr holds the parsed multicast address to which messages should be sent.
But since each port can have a different scope, and the primary MC address
depends on the scope, it really can't be stored in a global variable. Move both
to struct udp6.
Additionally, document the fact that the primary
Black-box switches with PTP support commonly provide per-port statistics of
number of messages sent and received, split by the message type. Like other
statistics (ip link, ethtool, etc. etc.), network operators use the PTP
message stats to monitor the (PTP) network and debug issues.
When ptp4l
Add an ability of pmc to query per-port stats added in the previous patch.
