Subject: [PATCH iproute2] iplink: Added support for the kernel IPoIB RTNL ops
Added support to ipoib rtnl ops through which one can create, configure,
query and delete IPoIB devices, for example
$ ip link add link ib0.8001 name ib0.8001 type ipoib pkey 0x8001
$ ip link add link ib0.1 name ib0.1 type ipoib mode connected
$ ip --details link show dev ib0.1
