This allows one to create virtual interfaces that map packets to or from specific MAC addresses to a particular interface.
Macvlan devices can be added using the "ip" command from the iproute2 package starting with the iproute2-2.6.23 release:
ip link add link <real dev> [ address MAC ] [ NAME ] type macvlan
To compile this driver as a module, choose M here: the module will be called macvlan.

Provides a cgroup Resource Controller for HugeTLB pages.When you enable this, you can put a per cgroup limit on HugeTLB usage.The limit is enforced during page fault. Since HugeTLB doesn't support page reclaim, enforcing the limit at page fault time implies that, the application will get SIGBUS signal if it tries to access HugeTLB pages beyond its limit. This requires the application to know beforehand how much HugeTLB pages it would require for its use. The control group is tracked in the third page lru pointer. This means that we cannot use the controller with huge page less than 3 pages.
