Getting Tx Message Header: dalNbcsSswGetIlcTxHdr
Retrieves all header bits to be transmitted for a given port.
Getting Number of Messages in Rx FIFO: dalNbcsSswGetIlcRxNumMsg
Query the total number of messages currently stored in the Rx FIFO.
Getting Messages in Rx FIFO: dalNbcsSswGetIlcRxMsg
This function retrieves one or more ILC messages from the Rx FIFO of one or more ports (the
exact number is indicated by
each time this function is called.)
