Currently, in Auto mode, PUSH flag is set based on the application/network conditions. The system should instead append a PUSH flag to sub-MSS TCP segments (except 0 length pure ACK) to PUSH small segments faster to the receiving application in auto mode.
Non HTTP applications receive small segments slower if PUSH Flag is not present in sub-MSS TCP segments.
Non HTTP applications sending sub MSS packets.
None.
In Auto Mode, last sub-MSS TCP segments are always appended with PUSH flag.
