I think the large number of interrupts has nothing to do with axe(4). Almost all USB ethernet controllers are poorly designed to save cost so you can't expect reasonable performance from it and you should have fast CPU to copy received frames in a buffer. It's worse than rl(4) controllers.
Are there any that are better? I have several machines here that I will be using as embedded systems. They have one Ethernet interface each, and I need some of them to have two. The only other non-USB ports on these machines are video and CompactFlash. I've thought about using VLAN tagging and VLAN switch to double up the Ethernet port, but this is quite expensive. So, I need the best USB Ethernet I can get. I chose the AX88772A because it seems to be a better solution than the Davicom DM9601 (which is USB 1.0 only). The AX88178 has more buffer space, but I am having trouble finding reasonably priced adapters that use it. --Brett Glass _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-usb To unsubscribe, send any mail to "[email protected]"
