session: fix allocation of proxy fifos
Fifos need to be synchronously allocated once a transport like tcp accepts a session. Since events are now delivered asynchronously, proxy apps must explicitly register a cb function that manages fifo allocation prior to being notified of connect event. Type: fix Fixes: 0242d30 Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I7df973b7014e53e0766ea2bdc61e9871160bc18b
