RXTT
Rx time stamp valid. Equals 1b when a valid value for Rx time stamp
is captured in the Rx time stamp register; cleared by read of Rx time
stamp register RXSTMPH.
Type
Type of packets to timestamp:
000b = Time stamp L2 (V2) packets only (Sync or Delay_req depends
on message type in
and 3).
001b = Time stamp L4 (V1) packets only (Sync or Delay_req depends
on message type in
010b = Time stamp V2 (L2 and L4) packets (Sync or Delay_req
depends on message type in
message ID 2 and 3).
100b = Time stamp all packets (in this mode no locking is done to the
value in the time stamp registers and no indications in receive
descriptors are transferred).
101b = Time stamp all packets whose message id bit 3 is zero, which
means time stamp all event packets. This is applicable for V2 packets
only.
011b, 110b and 111b = Reserved.
En

0x0 = Time stamping disabled.
0x1 = Time stamping enabled.

RXSTMPH
Rx time stamp MSB value.
