IPoIB driver now uses the new set of callback functions.
If the hardware provider supports the new ipoib_options implementation,
the driver uses the callbacks in its data path flows, otherwise it uses the
driver default implementation for all data flows in its code.
The default implementation wasn't change and it is exactly as it was before
introduction of acceleration support.

This patch is preparing the netdev part at the IPoIB driver to be able
to use the ipoib_options.
It deals with the two flows from the .ndo: ipoib_open and ipoib_stop.
The code is rearranged as follows:
* All operations which deal with the hardware resources, (for example
change QP state, post-receive etc.) are performed in one place.
* All operations that are control oriented (like restart multicast task,
start the reap_ah etc.) are performed in separate place.
The functions that deal with the hardware resources now located at
__ipoib_ib_dev_open for the ipoib_open flow and __ipoib_ib_dev_stop
for ipoib_stop.

This patch prepares init and teardown flows so we can call them
through ipoib_options function pointers.
It arranges that area of code as the following:
* All operations which deal with the resource allocation/deletion
are performed in one place.
* All operations that are control oriented, meaning that they are not
connected to a specific hardware, are performed in a separate place.
The operations for allocation of hardware resources are now in the
function ipoib_dev_init_default, and the deletion of all the resources
are in ipoib_dev_uninit_default
The only exception is the creation of the PD object,
which is used both for resource allocation (create QP etc.)
and for control flows like creating AH.
It also does:
* Move creation of rx_ring and tx_ring to be in the resources
allocation area.
* Move the function ipoib_ib_dev_open that does the open device
to the control area instead of the dev_init which creates resources.

Add RDMA netdev interface to ib device structure allowing RDMA
netdev devices to be allocated by ib clients.
The idea is to allow to providers to optimize IPoIB data path.
New struct that includes functions and data member is exposed.
It exposes set of callback functions for handling data path flows
in IPoIB driver.
Each provider can support these set of functions in order
to optimize its specific data path, and let IPoIB to leverage
its data path.
There is an assumption, that providers should give the full set
of functions and not only part of them, in order to work properly.

HFI1 HW specific support for VNIC functionality.
Dynamically allocate a set of contexts for VNIC when the first vnic
port is instantiated. Allocate VNIC contexts from user contexts pool
and return them back to the same pool while freeing up. Set aside
enough MSI-X interrupts for VNIC contexts and assign them when the
contexts are allocated. On the receive side, use an RSM rule to
spread TCP/UDP streams among VNIC contexts.

OPA VEMA function interfaces with the Infiniband MAD stack to exchange the
management information packets with the Ethernet Manager (EM).
It interfaces with the OPA VNIC netdev function to SET/GET the management
information. The information exchanged with the EM includes class port
details, encapsulation configuration, various counters, unicast and
multicast MAC list and the MAC table. It also supports sending traps
to the EM.

OPA VNIC netdev function supports Ethernet functionality over Omni-Path
fabric by encapsulating Ethernet packets inside Omni-Path packet header.
It allocates a rdma netdev device and interfaces with the network stack to
provide standard Ethernet network interfaces. It overrides HFI1 device's
netdev operations where it is required.
