The P1010 device tree restricts the number of
supported interrupt groups to 1, although the eth
controller can support 2 interrupt groups and the
driver assumes the Multi-Group mode ("fsl,etsec2" model).

So, in this case the assumption that the Multi-Group
mode (MQ_MG_MODE) devices always support 2 interrupt
groups is false.  To fix this, a check for the actual
number of interrupt groups enabled in the board's
device tree has been added in gfar_probe for the
"fsl,etsec2" devices.

Without this fix, P1010 based boards claim support for
2 Tx queues to the net stack but only one is actually
allocated, leading to NULL access in xmit.  This issue
was introduced by enabling Single-Queue polling for
the P1010 devices.

Memory allocated for the MDIO bus with the devm_kzalloc() API is
associated with the network device. While this will cause memory to be
freed at the right time, it doesn't allow allocating memory before the
network device is initialized.

Replace the network device with the parent platform device for memory
allocation to remove that dependency. This also improves consistency
with the other devm_* calls in the driver that all use the platform
device.

This makes the generic of_mdiobus_register parse the DT compatible string for
the pattern ethernet-phy-idAAAA.BBBB. If present it should be a value that
matches the phy-id register normally readable through MDIO.

When the ID is given the phy autoprobing is defeated and the phy is
created directly.

This is necessary to support phy's that cannot be autoprobed when
of_mdiobus_register is called. Specifically, my case has the phy in reset at
of_mdiobus_register, the reset is only released once the ethernet driver
starts, before it attaches to the phy.

Adds support for N-Port VFs, this includes:
1. Adding support in the wrapped FW command
	In wrapped commands, we need to verify and convert
	the slave's port into the real physical port.
	Furthermore, when sending the response back to the slave,
	a reverse conversion should be made.
2. Adjusting sqpn for QP1 para-virtualization
	The slave assumes that sqpn is used for QP1 communication.
	If the slave is assigned to a port != (first port), we need
	to adjust the sqpn that will direct its QP1 packets into the
	correct endpoint.
3. Adjusting gid[5] to modify the port for raw ethernet
	In B0 steering, gid[5] contains the port. It needs
	to be adjusted into the physical port.
4. Adjusting number of ports in the query / ports caps in the FW commands
	When a slave queries the hardware, it needs to view only
	the physical ports it's assigned to.
5. Adjusting the sched_qp according to the port number
	The QP port is encoded in the sched_qp, thus in modify_qp we need
	to encode the correct port in sched_qp.

This patch moves the call to enable Tx queues after the link is established.
Previously there was a chance for aggressive start_ndo_xmit() callers to
sneak packets between enabling the Tx queues and the link coming up.

In addition it replaces netif_tx_start_all_queues() with
netif_tx_wake_all_queues() to allow for flushing of the qdisc.

This patch fixes flow control autonegotiation for KR/KX/K4 interfaces.
When setting up MAC link, the cached autoc value and current autoc value
were being incorrectly used to determine whether link reset is required.
This resulted in the driver ignoring and discarding flow control
negotiation changes that occur since the caching happened, as well as
when the mac was being setup.

This patch also splits the assignments for the 3 autoc variables into
their own block, and adds a comment explaining what each one means, in
order to help keep logic more straightforward while reading the code.
