RE: Gigabit ethernet
And just to get my name in the minutes, the Intel Gig Ethernet card works fairly well, but because it's not well supported by the manufacturer releasing information about it, it may not be the best choice. Performance has been not proven to be good either- partly because I only had rev 1 boards that couldn't do PCI MWI cycles. I've had reports from other folks that have indicating being able to saturate a switch with it, but I have not been able to confirm that myself. FWIW.

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.) OK. And finally, netperf seems to work reasonably well for testing performance: http://www.netperf.org Cool. I've been using several tools, since we do our real performance testing with a SmartBits. I use spray to generate UDP traffic and a hacked-up version of tcpblast for tcp traffic.

Of all the gin joints in all the towns in all the world, David Malone had to walk into mine and say: On Wed, Aug 18, 1999 at 06:43:24PM -0400, Bill Paul wrote: Just out of curiosity, I thought I saw that you could get Intel Etherexpress 1Gb/s cards. Do these exist and if so would they work with the fxp driver as it is? David. The Intel gigabit ethernet cards are nothing like the EtherExpress fast ethernet adapters. Getting information out of Intel is like trying to squeeze blood from a stone. 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.

Do these exist and if so would they work with the fxp driver as it is? David. The Intel gigabit ethernet cards are nothing like the EtherExpress fast ethernet adapters. Getting information out of Intel is like trying to squeeze blood from a stone. 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.
