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 [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
Still waiting for xl driver reports
A while back I posted a message here saying that I'd changed the xl driver a bit to hopefully improve performance for 3c90xB and later adapters (i.e. the "cyclone," "hurricane" and "tornado" chipsets). I asked for people to report if the changes helped, hurt, made no difference or were totally broken. So far not one person has said so much as a word to me on this subject. I need feedback from people so that I know it's safe to merge this stuff into -stable, so let's hear it already. It's been several weeks since I made the changes. Surely there are people running -current with 3Com 3c90xB cards. To reiterate, this only concerns people with the following adapters: - 3c905B-TX 10/100 - 3c905B-FX/SC fiber optic - 3c905B-COMBO 10/100 plus BNC and AUI - 3c905C-TX 10/100 - 3c980-TX server adapter - 3c980B-TX server adapter - 3c980C-TX server adapter - 3cSOHO100-TX 10/100 To a lesser extent it also concerns people with these adapters (these are 10Mbps only so the change isn't likely to be as noticable): - 3c900B-TPO twisted pair only - 3c900B-TPC twisted paid and coax (BNC) - 3c900B-COMBO twisted pair, AUI and BNC - 3c900B-FL fiber optic Ideally, the changes should provide slightly faster performance with less CPU usage. Performance/CPU overhead comparisons with other cards (in the same machine!) would he helpful as well as comparisons with the same 3Com card using the older driver revision. Things that would not be helpful include: - Asking about an unrelated problem from 3.2-RELEASE, 3.3-RELEASE or 3.3-STABLE. - Telling me that your card isn't detected properly and not realizing that you have "plug and play OS" set to "yes" in your BIOS config. - Asking about a completely different card. From a completely different manufacturer. - Saying that you'll be happy to run some tests "as soon as you find some time." If you couldn't find the time by now, you never will. - Giving me an excuse for not sending me any feedback earlier. I don't care if your dog got run over, your house was invaded by giant ants, your entire family contracted the bubonic plague or aliens stole your computer. - Asking me how to set up a 3Com card in Linux. (Comparing the xl driver's performance with the Linux 3Com driver is acceptable, provided you run the comparison on the same hardware. Comparing a PIII 600Mhz host running Linux to a PII 300Mhz host running FreeBSD is not a fair comparison. Unless FreeBSD ends up being faster. :) -Bill -- = -Bill Paul(212) 854-6020 | System Manager, Master of Unix-Fu Work: [EMAIL PROTECTED] | Center for Telecommunications Research Home: [EMAIL PROTECTED] | Columbia University, New York City = "It is not I who am crazy; it is I who am mad!" - Ren Hoek, "Space Madness" = To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
