under show controller serial what does sdma mpsc mean

I know that mpsc is a multi protocol serial controller, and that the sdma is an interface, but i am unsure of what all the other parts of those fields mean.

204546309 mpsc_rx, 1 mpsc_rxerr, 26859 mpsc_rlsc, 93514 mpsc_rhnt, 204482754 mpsc_rfsc

4229 mpsc_rcsc, 1 mpsc_rovr, 0 mpsc_rcdl, 0 mpsc_rckg, 0 mpsc_bper

0 mpsc_txerr, 64341501 mpsc_teidl, 0 mpsc_tudr, 0 mpsc_tctsl, 0 mpsc_tckg

0 sdma_rx_sf, 2 sdma_rx_mfl, 15148 sdma_rx_or, 52110 sdma_rx_abr, 40725 sdma_rx_no

0 sdma_rx_de, 0 sdma_rx_cdl, 109827 sdma_rx_ce, 0 sdma_tx_rl, 0 sdma_tx_ur, 0 sdma_tx_ctsl

1 sdma_rx_reserr, 0 sdma_tx_reserr

0 rx_bogus_pkts, rx_bogus_flag FALSE

0 sdma_tx_ur_processed

Re: under show controller serial what does sdma mpsc mean

This interface never hit the tx limit. The "y" count is the number of times we exceeded the tx limit. "x" is the count of tx ring entries used and the middle number 60 is the allowed maximum tx packet in tx queue. Unless we know that the hold-queue is holding some packets or we are limited to one packet at a time on the tx ring (in case of congestion) and

the tx ring is not empty, we will not queue the packet to hold-queue.tx enqueued is the number of packets qued for transmission
