TX vs RX pause frame question

2017-03-26 Thread Benjamin Herrenschmidt
Hi ! It's not 100% clear to me looking at various drivers what is considered "rx_pause" and what is "tx_pause" (from the ethtool terminology). Is "rx_pause" about receiving pause frame to throttle the transmitter or is it about sending pause frames when the receiver gets full ? Thanks, Ben.
