This is under linux 2.4.20-pre11. The card is connected to an ixia test box. I captured some arps and Ixia claims the header is a CISCO ISL header instead of getting an 802.1q header. I've copied the header below. I've tried to break it up by fields. CISCO ISL header 01 00 0C 00 00 00 Dst address 00 03 47 9B 67 CB Src Address 00 3A Len AA AA 03 Magic number? 00 03 47 01 90 Vlan ID (200) 00 00 00 00 Ethernet header FF FF FF FF FF FF 00 03 47 9B 67 CB 08 06 Arp Header 00 01 08 00 06 04 00 01 00 03 47 9B 67 CB Sender Address C8 01 02 01 Sender IP 200.1.2.1 00 00 00 00 00 00 Target Address C8 01 02 02 Target IP 200.1.2.2 Has anybody else seen anything like this? I tried the same test on an intel eep100 with vlans enabled and everything looks fine. I've tried to different gig-e cards, both 82543, and both act the same way. Thanks, Jon
