IB/ipoib: Add rtnl_link_ops support
Add rtnl_link_ops to IPoIB, with the first usage being child device create/delete through them. Childs devices are now either legacy ones, created/deleted through the ipoib sysfs entries, or RTNL ones. Adding support for RTNL childs involved refactoring of ipoib_vlan_add which is now used by both the sysfs and the link_ops code. Also, added ndo_uninit entry to support calling unregister_netdevice_queue from the rtnl dellink entry. This required removal of calls to ipoib_dev_cleanup from the driver in flows which use unregister_netdevice, since the networking core will invoke ipoib_uninit which does exactly that.

Datagram vs Connected modes
The IPoIB driver supports two modes of operation: datagram and
