session: cleanup session tx function
- rework the function to declutter and avoid building more than one tx frame - add dual loop although benefits in my tests seem to be minimal - improve tcp/udp echo external apps. They have slightly better throughput than internal echo apps. - udp bugfixes Change-Id: Iea4a245b1b1bb407a7f403dedcce2664a49f774b Signed-off-by: Florin Coras <fcoras@cisco.com>
