Querying Free Space in ILC Tx FIFO: nbcsIlcGetTxFifoLvl
This function is to check the current capacity of the Tx FIFO for the given device and link. This
allows the user to find out how many more messages can be written to FIFO for transmission.
When the NSE is the transmitting device, the handle of the remote SBS can be given (via
rxHandle
to the intended SBS. The parameter
and
linkDesc
) instead of parameter
