RWSY FN: SYNCxxx [TYPE:x] -- Source TCP SYNC/RESYNC Trace Point

This source-side trace point records various commands and replies flown in the execution of TCP/IP two-phase commit operations.

The segment of the data represented by the preceding 'xxx' can be:

CTL, representing a control command
RSY, representing a resync command
CRD, representing reply data from a control command
RRD, representing reply data from a resync command

For the CTL and RSY records, there is also a TYPE code associated with the commands. It is not a printable character, so it is observable only in the hexadecimal data part of the record. It follows the string 'TYPE:'.
