Better would be /* Enable reception of 802.3x pause frames. */. My soekris boxes are connected to a slow so called "Ethernet Connect" line (2 Mbit/s). The line works correct and stable if I respect incoming RX pause frames from the line. I do not need TX flow-control. > Try attached patch and let me know how it works. Thanks for your patch. I will test it on next update of my soekris boxes with sis interfaces. Because they are all remote far away this will need some time. -- Andreas Longwitz
