tcp: export packets delivery info
Export data delivered and delivered with CE marks to 1) SNMP TCPDelivered and TCPDeliveredCE 2) getsockopt(TCP_INFO) 3) Timestamping API SOF_TIMESTAMPING_OPT_STATS Note that for SCM_TSTAMP_ACK, the delivery info in SOF_TIMESTAMPING_OPT_STATS is reported before the info was fully updated on the ACK. These stats help application monitor TCP delivery and ECN status on per host, per connection, even per message level.
