Enabling E-Switch SRIOV for nvfs+1 vports.
Create E-Switch FDB for L2 UC/MC mac steering between VFs/PF and
external vport (Uplink).
FDB contains forwarding rules such as:
UC MAC0 -> vport0(PF).
UC MAC1 -> vport1.
UC MAC2 -> vport2.
MC MACX -> vport0, vport2, Uplink.
MC MACY -> vport1, Uplink.
For unmatched traffic FDB has the following default rules:
Unmached Traffic (src vport != Uplink) -> Uplink.
Unmached Traffic (src vport == Uplink) -> vport0(PF).
FDB rules population:
Each NIC vport (VF) will notify E-Switch manager of its UC/MC vport
context changes via modify vport context command, which will be
translated to an event that will be handled by E-Switch manager (PF)
which will update FDB table accordingly.

E-Switch is the software entity that represents and manages ConnectX4
inter-HCA ethernet l2 switching.
E-Switch has its own Virtual Ports, each Vport/vNIC/VF can be
connected to the device through a vport of an e-switch.
Each e-switch is managed by one vNIC identified by
HCA_CAP.vport_group_manager (usually it is the PF/vport[0]),
and its main responsibility is to forward each packet to the
right vport.
e-Switch needs to manage its own l2-table and FDB tables.
L2 table is a flow table that is managed by FW, it is needed for
Multi-host (Multi PF) configuration for inter HCA switching between
PFs.
FDB table is a flow table that is totally managed by e-Switch driver,
its main responsibility is to switch packets between e-Swtich internal
vports and uplink vport that belong to the same.
This patch introduces only e-Swtich l2 table management, FDB managemnt
will come later when ethernet SRIOV/VFs will be enabled.

This patch adds SRIOV base support for mlx5 supported devices. The same
driver is used for both PFs and VFs; VFs are identified by the driver
through the flag MLX5_PCI_DEV_IS_VF added to the pci table entries.
Virtual functions are created as usual through writing a value to the
sriov_numvs sysfs file of the PF device. Upon instantiating VFs, they will
all be probed by the driver on the hypervisor. One can gracefully unbind
them through /sys/bus/pci/drivers/mlx5_core/unbind.
mlx5_wait_for_vf_pages() was added to ensure that when a VF dies without
executing proper teardown, the hypervisor driver waits till all of the
pages that were allocated at the hypervisor to maintain its operation
are returned.
In order for the VF to be operational, the PF needs to call enable_hca
for it. This can be done before the VFs are created through a call to
pci_enable_sriov.
If the there are VFs assigned to a VMs when the driver of the PF is
unloaded, all the VF will experience system error and PF driver unloads
cleanly; in this case pci_disable_sriov is not called and the devices
will show when running lspci. Once the PF driver is reloaded, it will
sync its data structures which maintain state on its VFs.

This change makes it so that we allow the PF to make use of all free RAR
entries for FDB use if needed.
Previously the code limited us to 16 unicast entries, however this was
shared between MACVLAN which wasn't limited and the FDB code which was. So
instead of treating the FDB code as a second class citizen I have updated
it so that it has access to just as many entries as the MACVLAN filters.

In the process of tracking down a memory leak when adding/removing FDB
entries I had to go through the MAC address configuration code for ixgbe.
In the process of doing so I found a number of issues that impacted
readability and performance. This change updates the code in general to
clean it up so it becomes clear what each step is doing. From what I can
tell there a couple of bugs cleaned up in this code.
First is the fact that the MAC addresses were being double counted for the
PF. As a result once entries up to 63 had been used you could no longer
add additional filters.
A simple test case for this:
for i in `seq 0 96`
do
ip link add link ens8 name mv$i type macvlan
ip link set dev mv$i up
done
Test script:
ethregs -s 0:8.0 | grep -e "RAH" | grep 8000....$
When things are working correctly RAL/H registers 1 - 97 will be consumed.
In the failing case it will stop at 63 and prevent any further filters from
being added.
