I have installed two AceNIC (gigabit Enet) PCI cards in a machine I'm working with and I've cabled them together by connecting each one's Tx port to the other's Rx port. The driver seems to be happy with what it finds and the cards seem to be aware of each other on the link: >eth4: Alteon AceNIC Gigabit Ethernet at 0xd6000000, irq 21 > Tigon II (Rev. 6), Firmware: 12.4.11, MAC: 00:60:cf:20:55:52 > PCI bus width: 32 bits, speed: 33MHz, latency: 64 clks >eth4: Firmware up and running > >eth5: Alteon AceNIC Gigabit Ethernet at 0xd2000000, irq 24 > Tigon II (Rev. 6), Firmware: 12.4.11, MAC: 00:60:cf:20:51:d1 > PCI bus width: 32 bits, speed: 33MHz, latency: 64 clks >eth5: Firmware up and running > >eth5: Optical link UP >eth4: Optical link UP I can ifconfig them just fine, each with their own IP addrs, and I've jiggered around with the routing tables in semi-clueless fashion, but I can't figure out how to trick the kernel into sending data over the wire (fibre, actually). It seems that the kernel is just too smart for me and notices that the destination of any transfer I attempt through one of those interfaces is an interface known to be local, so it just hands the the transfer over to the destination interface rather than pushing the bits over the wire. So, my question is: how can I exercise these cards by having them shoot data back and forth to each other? ********************************************************** To unsubscribe from this list, send mail to [EMAIL PROTECTED] with the following text in the *body* (*not* the subject line) of the letter: unsubscribe gnhlug **********************************************************
