I have posted a patch against iproute2/tc, that implement reading out the linklayer setting (requires my kernel patch discussed in this thread). See: http://thread.gmane.org/gmane.linux.network/281876 This patch also sends the linklayer option to the kernel directly, which mean that the kernel don't need to perform linklayer detection based on the rate table (which were not accurate at rates above 100Mbit/s). -- Best regards, Jesper Dangaard Brouer MSc.CS, Sr. Network Kernel Developer at Red Hat Author of http://www.iptv-analyzer.org LinkedIn: http://www.linkedin.com/in/brouer
