Merge branch 'net-protodown-support-for-macvlan-and-vxlan' 



Andy Roulin says:

====================
net: protodown support for macvlan and vxlan

This patch series adds dev_change_proto_down_generic, a generic
implementation of ndo_change_proto_down, which sets the netdev carrier
state according to the new proto_down value.

This handler adds the ability to set protodown on macvlan and vxlan
interfaces in a generic way for use by control protocols like VRRPD.

Patch (1) introduces the handler in net/code/dev.c. Patch (2) and (3) add
support for change_proto_down in macvlan and vxlan drivers, respectively,
using the new function.
