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.

Like the mlx5e ethernet mode, on IPoIB mode we need to create RX steering
tables, but IPoIB do not require MAC and VLAN steering tables so the
only tables we create in here are:
1. TTC Table (Traffic Type Classifier table for RSS steering)
2. ARFS Table (for accelerated RFS support)
Creation of those tables is identical to mlx5e ethernet mode, hence the
use of mlx5e_create_ttc_table and mlx5e_arfs_create_tables.

Pull virtio fixes from Michael S. Tsirkin:
"virtio oops fixes
The virtio pci rework using shared interrupts caused a lot of issues.
We tried to fix them but run out of time. Revert for now, and revisit
the issue for the next kernel.
Luckily we are able to do this without loosing automatic interrupt
NUMA affinity which was the main motivator for the rework"
* tag 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mst/vhost:
virtio-pci: Remove affinity hint before freeing the interrupt
Revert "virtio_pci: remove struct virtio_pci_vq_info"
Revert "virtio_pci: use shared interrupts for virtqueues"
Revert "virtio_pci: don't duplicate the msix_enable flag in struct pci_dev"
Revert "virtio_pci: simplify MSI-X setup"
Revert "virtio_pci: fix out of bound access for msix_names"
MAINTAINERS: fix virtio file pattern
virtio_console: fix uninitialized variable use
virtio_net: clear MTU when out of range
virtio: allow drivers to validate features
virtio_net: enable big packets for large MTU values
