Subject: [PATCH] retain ABI definitions for obsolete multi-queue packet
 schedulers

Even though the sch_rr qdisc is now gone in 2.6.27, the kernel
definitions for the attributes need to be maintained because applications
like iproute need to be compatible with older kernels and use santized
kernel headers.
