Querying Free Space in ILC Tx FIFO: dalNbcsSswGetIlcTxFifoLvl
This function is to check the current capacity of the Tx FIFO. This allows the user to find out
how many more messages can be written to FIFO for transmission.
Setting Tx Message Header: dalNbcsSswSetIlcTxHdr
Sets LINK, AUX and optionally the PAGE and/or USER bits in the transmit header for a given
port. If the PAGE and/or USER bits have to be changed in a coordinated fashion across all ports,
set the arguments
