[patch net-next V3,repost 0/4] net: allow to change carrier from userspace

[Jiri Pirko <jiri@resnulli.us>]

This is basically a V3 of a repost of my previous patchset:
"[patch net-next-2.6 0/2] net: allow to change carrier via sysfs" from Aug 30

The way net-sysfs stores values changed and this patchset reflects it.
Also, I exposed carrier via rtnetlink iface.

So far, only dummy driver uses carrier change ndo. In very near future
team driver will use that as well.

V2->V3:
 - updated ndo_change_carrier comment by Dan Williams

V1->v2:
 - added bigger comment to ndo and also note to operstate.txt documentation
   stating the clear purpose of this iface

Jiri Pirko (4):
  net: add change_carrier netdev op
  net: allow to change carrier via sysfs
  rtnl: expose carrier value with possibility to set it
  dummy: implement carrier change
