I use the xl device (two cards: xl0 and xl1) in my kernel (compiled on October 4th) and hadn't realized I was using the new driver. I only noticed weird things last Sunday when the interface hung while I was trying a tcpdump on it (I was loggued remotely, which explains why I saw the problem immediately)... Then there was a "xl1: watchdog timeout" and things went back to normal. I compiled today's kernel to see if it made any difference, and I can confirm I can repeat it easily you wish. The watchdog timeout seems to happen every time I get out of promiscuous mode, and (very seldom) at other random moments. > To reiterate, this only concerns people with the following adapters: Here's what I have: xl0: <3Com 3c900-COMBO Etherlink XL> irq 11 at device 10.0 on pci2 xl0: Ethernet address: 00:10:5a:bf:13:96 xl0: selecting 10baseT transceiver, half duplex xl1: <3Com 3c905B-TX Fast Etherlink XL> irq 11 at device 17.0 on pci0 xl1: Ethernet address: 00:c0:4f:67:0b:82 It's on xl1 that I have problems, although I'm not sure this wouldn't happen on xl0 too (xl0 is configured down at the moment). Now regarding performance, I haven't made extensives tests. The closest thing to that that I have in mind is to stretch that 2*100Mbps trunking link we configured this morning between two of our ethernet switches :-) -- Pierre Beyssac pb@enst.fr To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
