BytesTo marshalls packets that support this optimized marshalling into []byte

Compare returns an integer comparing two port identities. The result will be 0 if p == q, -1 if p < q, and +1 if p > q. The definition of "less than"

DefaultPiServoFilterCfg to create a default pi servo filter config

Followup returns ptp Follow Up packet
