Each Vport/vNIC must notify underlying e-Switch layer
for UC/MC list and promisc mode updates, in-order to update
l2 tables and SR-IOV FDB tables.
We do that at set_rx_mode ndo.

In preparation for SR-IOV we add here an API to enable each e-switch
client (PF/VF) to configure its L2 MAC addresses and for the e-switch
manager (usually the PF) to access them in order to be able to
configure them into the e-switch.
Therefore we now pass vport num parameter to
mlx5_query_nic_vport_context, so PF can access other vports contexts.

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.

Lower layer (pci) has information if the packet is received via LAG port.
If that is the case, it fills up rx_info accordingly. However upper
layer does not care about lag_id/port_index for received packets so
convert it to local_port before passing it up. For that conversion, lag
mapping array is introduced. Upper layer is responsible for setting up
the mapping according to what is set in HW.

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.

This change replaces the ixgbe_write_uc_addr_list call in ixgbe_set_rx_mode
with a call to __dev_uc_sync instead. This works much better with the MAC
addr list code that was already in place and solves an issue in which you
couldn't remove an FDB address without having to reset the port.

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.
