Detailed Description

Tx SAR Table (TSt) Structure to manage the transmitted data stream in the TCP Tx buffer memory. Every session is allocated with a static Tx buffer of 64KB to store the stream of bytes received from the application layer, until the network layer consumes (.i.e read) them out and acknowledge them. The Tx buffer is managed as a circular buffer with three pointers:

'appw' points to the last byte written by the application layer.
'ackd' holds the sequence number of the last transmitted and acknowledged byte by the network layer (aka SND.NXT),
'unak' holds the sequence number of the last transmitted but not yet acknowledged byte by the network layer (aka SND.UNA).
```
