Subject: [PATCH] if: restore token ring ARP type to header

From: Stephen Hemminger <[email-masked]>
Date: Tue, 22 May 2012 14:01:05 -0700

Recent removal of Token Ring breaks the build of iproute2.

Even though Token Ring support is gone from the kernel, it is worth
keeping the the definition of the TR ARP type to avoid breaking
userspace programs that use this file.
