Possible responses & paths from the Phy while receiving a packet
start_Rx
Ignoring intermediate abort reevaluations
No Sync
AddrFound
Not a real path as we scan with infinite length
Always accepted
End
Header error
Not Possible
due to request params.
OK
Packet failed
Draw CI failure
CI OK
start_Rx2
No Sync
(Due to Tx disapearing )
=> Set CRC/Payload end and let main FSM continue without Phy Rx
AddrFound
FEC2
FEC1 
Continues like normal
packet after AddrFound
CODED PHY
start_Rx
No Sync
AddrFound
Not a real path as we scan with infinite length
End
Header error
OK
Packet failed
Normal packet (not CODED PHY)
Incorrect length or CI
=> Reject Phy packet, let main FSM continue without Phy Rx
Accept packet
Almost same behaviour, as packet failed, except that CRC end time is based on a provisional guess
