Queue Allocate/Data Block Processor:1 Gbps mode extensions

• Queue allocate (QA) message processing:

  • Increments the Transmit Pending Array (TPA) 4-bit value that corresponds to the source port ID (SPID) and priority.

• Data block (DB) message processing:

  • Notifies the Queue Fetch Scheduler, passes EOF status.
  • If EOF=1, decrements the corresponding Transmit Pending Array value.
  • Passes the DB through to the TxCTRL Framer Reassembly Bugger Interface for statistics gathering.
