As an aside, there are bound to be extra problems with the Intel gigabit NICs because, if I'm not mistaken, then use an on-board i960 processor to drive them. This means that in order to make the NIC work, you have to load firmware into it, and with firmware comes sticky licensing issues. The Alteon Tigon chipset also requires firmware (it has embedded MIPS R4000 CPUs) but Alteon actually released the firmware source code along with all the other Tigon development information. They even have a mailing list where you can send in questions regarding the firmware and get answers from a real live developer. Until such time as Intel gets its head out of its ass in this regard, I refuse to have anything to do with their networking products, especially when I have two other sources of perfectly good gigabit ethernet NICs available to me with full, unencumbered documentation. Initially this was not true of SysKonnect: they had a Linux driver for their cards but no programming info available. Much to my surprise, after a lengthy e-mail discussion, they actually agreed to release the manual for their GEnesis ASIC not just to me but to anybody without NDA on their web site. You would think that Intel would be prepared to make the same commitment to their customers, but so far as I know, they're still stuck in their proprietary ways. -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-hackers" in the body of the message

Either they want you to sign a non disclosure agreement that prevents you from releasing driver source (or makes it hard) or they won't give you any information at all. Sometimes they also play a different game where they release some information and pretend they're being 'open' but in reality the stuff they release is just fluff and you still have to sign an NDA to get your hands on the good stuff. As an aside, there are bound to be extra problems with the Intel gigabit NICs because, if I'm not mistaken, then use an on-board i960 processor to drive them. This means that in order to make the NIC work, you have to load firmware into it, and with firmware comes sticky licensing issues. The Alteon Tigon chipset also requires firmware (it has embedded MIPS R4000 CPUs) but Alteon actually released the firmware source code along with all the other Tigon development information. They even have a mailing list where you can send in questions regarding the firmware and get answers from a real live developer. Until such time as Intel gets its head out of its ass in this regard, I refuse to have anything to do with their networking products, especially when I have two other sources of perfectly good gigabit ethernet NICs available to me with full, unencumbered documentation. Initially this was not true of SysKonnect: they had a Linux driver for their cards but no programming info available. Much to my surprise, after a lengthy e-mail discussion, they actually agreed to release the manual for their GEnesis ASIC not just to me but to anybody without NDA on their web site. You would think that Intel would be prepared to make the same commitment to their customers, but so far as I know, they're still stuck in their proprietary ways. -Bill -- = -Bill Paul(212) 854-6020 | System Manager, Master of Unix-Fu Work: wp...@ctr.columbia.edu | Center for Telecommunications Research Home: wp...@skynet.ctr.columbia.edu | 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 majord...@freebsd.org with unsubscribe freebsd-hackers in the body of the message

Any supported cards in 3.2.x? The HCL pages don't list any:( The ti driver supports several cards, including the Alteon AceNIC, the 3Com 3c985-SX, the Netgear GA620, the DEC EtherWORKS 1000, the SGI PCI gigabit ethernet card, the NEC gigabit ethernet card and possibly some from IBM as well, though I don't know the PCI vendor/device IDs for those so I can't be sure (if you find them out, you can try hacking them into the driver). All of these are supported by the same driver because they're all OEMed from Alteon. We have two of the NetGear GA620's here, and they work quite nicely. I use them for testing throughput via Gig-E on our switches. Mine is running in a lowly PII/233, on a 32-bit x 33 Mhz slot, and can push bits at 320 Mbps. The GA620 will work in any 32 or 64 bit, 33 or 66 Mhz slot. A 64x66 slot would probably speed things up appreciably. I doubt a faster PCI interface would really speed things up. My guess is that you've got some other bottleneck other than PCI bandwidth. Is the CPU pegged on either end? I would recommend that you make sure you've got a couple of things tweaked, they may increase your performance somewhat: - set your MTU to 9000, unless of course you're going through a switch that can't handle it - turn on net.inet.tcp.rfc1323, it enables support for TCP windows larger than 64K - increase net.inet.tcp.sendspace and net.inet.tcp.recvspace to 256K. You'll have to edit src/sys/socketvar.h and increase SB_MAX. From what I've seen (this may not be quite correct, but it's close enough) SB_MAX has to be double whatever you want to set sendspace and recvspace to. This has the effect of changing the TCP window size to 256K, I think. From what I've seen, increasing it to 512K is counterproductive unless you've got a card with 1MB of SRAM on board. (The Netgear boards have 512K.) And finally, netperf seems to work reasonably well for testing performance: http://www.netperf.org They're relatively cheap, too, going for $339 at DataComm Warehouse. FWIW, NECX has them for $310. Ken -- Kenneth Merry k...@kdm.org To Unsubscribe: send mail to majord...@freebsd.org with unsubscribe freebsd-hackers in the body of the message
