MTL Rx Queue Write Controller Active Status When high, this bit indicates that the MTL Rx Queue Write controller is active, and it is transferring a received packet to the Rx Queue.

0 (Val_0x0): MTL Rx Queue write controller active status not detected

1 (Val_0x1): MTL Rx Queue write controller active status detected

MTL Rx Queue Read Controller State This field gives the state of the Rx Queue Read controller:

0 (Val_0x0): Idle state

1 (Val_0x1): Reading packet data

2 (Val_0x2): Reading packet status (or timestamp)

3 (Val_0x3): Flushing the packet data and status

MTL Rx Queue Fill-Level Status This field gives the status of the fill-level of the Rx Queue:

0 (Val_0x0): Rx Queue empty

1 (Val_0x1): Rx Queue fill-level below flow-control deactivate threshold

2 (Val_0x2): Rx Queue fill-level above flow-control activate threshold

3 (Val_0x3): Rx Queue full

Number of Packets in Receive Queue This field indicates the current number of packets in the Rx Queue. theoretical maximum value for this field is 256KB/16B = 16KB Packets, that is, Max_Queue_Size/Min_Packet_Size.
