This patch adds in the infrastructure code to create the network priority cgroup. The cgroup, in addition to the standard processes file creates two control files: 1) prioidx - This is a read-only file that exports the index of this cgroup. This is a value that is both arbitrary and unique to a cgroup in this subsystem, and is used to index the per-device priority map 2) priomap - This is a writeable file. On read it reports a table of 2-tuples <name:priority> where name is the name of a network interface and priority is indicates the priority assigned to frames egresessing on the named interface and originating from a pid in this cgroup This cgroup allows for skb priority to be set prior to a root qdisc getting selected. This is benenficial for DCB enabled systems, in that it allows for any application to use dcb configured priorities so without application modification Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: John Fastabend <john.r.fastabend@intel.com> CC: Robert Love <robert.w.love@intel.com> CC: "David S.
