From 211ed865108e24697b44bee5daac502ee6bdd4a4 Mon Sep 17 00:00:00 2001 From: Paul Gortmaker Date: Thu, 10 May 2012 17:14:35 -0400 Subject: net: delete all instances of special processing for token ring We are going to delete the Token ring support. This removes any special processing in the core networking for token ring, (aside from net/tr.c itself), leaving the drivers and remaining tokenring support present but inert. The mass removal of the drivers and net/tr.c will be in a separate commit, so that the history of these files that we still care about won't have the giant deletion tied into their history.
