I find that if the interface auto negotiates, it picks 100Mbit/FDX which matches the switch, but transfers are very bursty. If I force half duplex 100 or 10 mbit it works as I would expect (unbursty..). 10mbit/FDX is bursty as well. The switch is an Alloy NS-16J (http://www.alloy.com.au/products/ns16J.htm), and it works fine with other ethernet cards (Alloy 1430TX - http://www.alloy.com.au/products/Alloy1430.htm, and an Intel Etherexpress 10/100 in my laptop, plus various 10mbit PCMCIA cards) if_vr.c is at version 1.26.2.13 which I believe is quite recent, and most of the changes in -current after the MFC are not duplex related (from what I could see) Does anyone have any patches, or ideas/suggestions?
