This crap is because the driver has some vendor specific code to do failover on the dual port versions of the driver. Since SysKonnect was big in the FDDI world, I suspect they wanted the same management features in their gigabit cards. You have some choices: 1) use a different card 2) comment out the code in the sk98lin driver that generates and receives the management frames 3) use 2.6 and the skge driver that works on the same hardware. 4) backport the skge driver to 2.4. > I would appreciate any info to some resources.
