2022-01-10session: deschedule sessions with no data to sendFlorin Coras2-2/+26
This ensures the scheduler always tracks sessions that are descheduled, i.e., do not have events in the old io events list. When app retries to send, clear descheduled flag and potentially the pacer. Consequently, transports no longer need to reset the pacer when sessions are rescheduled after a long app tx pause. This also fixes a tcp bug whereby the pacer was reset too often when snd_una was equal to snd_nxt as there was no way to distinguish betwen app tx breaks and congestion.

Defaulting to /run/vpp/app_ns_sockets/${ns_id} (2) If a netns is passed, the sock_name has to be abstract (i.e. start with '@'). It will default to `@vpp/session/${ns_id}` and will be created in the provided netns.
