I just loaded 4.5-RELEASE, and cvsup/make world upgraded to 4.6-STABLE dated June 17, and have 2 machines with 3C996B-T cards using the bge driver with the two machines connected directly to each other using a crossover cable. Machines are both "home made" with Supermicro mobos with 1.2GHz CPUs. Using /dev/zero I created a file some 1.2 GBytes in size. I am getting 7 MBytes/s using scp and 30 MBytes/s using ftp. So, it looks like the max is about 240 Mbits/s. This is why we affectionately call gigabit Ethernet "a couple-hundred megabit ethernet", and we cant wait for Ken's zero copy code to reach -STABLE :) This test also includes tweaking the tcp and udp send and recv space buffers to 512K, by the way... I have not seen the error message or problem you indicated below. Not that this helps you fix your problem any, but I wanted to let you know that these cards and the bge driver does appear to work - at least for me. Let me know if you need further specifics on my setup, or want me to try anything else. --Lee > -----Original Message----- > From: Fabien THOMAS [mailto:fabien.thomas@netasq.com] > Sent: Wednesday, June 19, 2002 1:47 AM > To: paleph@pacbell.net > Cc: freebsd-net@FreeBSD.ORG > Subject: Re[2]: bge driver issue > > > I've the same problems and i fixed partially the problem by bumping > the return ring count. > > #define BGE_RETURN_RING_CNT 1024 > -> > #define BGE_RETURN_RING_CNT 2048 > > i dont think it is THE solution but it works better than > before for me... > > ppn> We have a Dell poweredge 2650 (successor to 2550). > > ppn> We also saw the same problem with 4.5.
