+ With ramp-up, without reset, with session verification.
+ Uses the same profile as pps tests.
+ Ramp up duration is not specified, as duration is computed.
+ Timeout tracking with automated ramp-up.
+ Correct computation of next duration.
+ Checking both early and late sessions.
+ No loss measurement also acts as a ramp-up.
+ Return ReceiveRateMeasurement from send_traffic_on_tg_internal,
as that is needed for detecting whether trial is ok as ramp up.
- Udp needs quite low ramp-up rate after recent regression.
- Max scale has higher rate (so failing) to avoid session timeouts.
+ Bump copyright year.
