I thought that some degree of compatibility was 
expected.  At the very least the newest version 
of "tc" must work on _any_ kernel as least as 
well as the version it replaces did.

I also though newer kernels should work older
version of iproute2, albeit without the features
added in the newer versions.

Are you saying this is not so?
