Sit is used for Ipv6 in IPv4 encapsulation. For example my ADSL provider does IPv6, as do I but the telco in the middle still thinks the internet is "neat" and hasn't progressed this far. I use sit0 to send packets off my lan to the outside world. sit0 wraps the Ipv6 packet in an ipv4 packet and sends the ipv4 packet to the ipv4 layer then across the telco dslam and atm to the providers box, which removes the ipv4 and treats the ipv6 properly. If you had Ipv6 and the ibm qeth layer doesn't handle ipv6 (It may do it directly I dont know) you could do the same. If you don't care about ipv6, just ignore it.
