For designs where EEPROMs are not connected to PCI Yukon2
chips we need to get the MAC address from the firmware.
Add a module parameter called 'mac_address' for this. It
will be used if no DT node can be found and the B2_MAC
register holds an invalid value.

Both new_steering_entry() and existing_steering_entry() return values
based on their success or failure, but currently they fall through
silently. This can make troubleshooting difficult, as we were unable
to tell which one of these two functions returned errors or
specifically what code was returned. This patch remedies that
situation by passing the return codes to err, which is returned by
mlx4_qp_attach_common() itself.
This also addresses a leak in the call to mlx4_bitmap_free() as well.

The size of the MAC register dump used to be the size specified by the
reg property in the device tree. Userland has no good way of finding
out that size, and it was not specified consistently for each MAC type,
so ethtool would end up printing junk at the end of the register dump
if the device tree didn't match the size it assumed.
Using the new version numbers indicates unambiguously that the size of
the MAC register dump is dependent only on the MAC type.

Commit 96249d70dd70 ("IB/core: Guarantee that a local_dma_lkey
is available") allows ULPs that make use of the local dma key to keep
working as before by allocating a DMA MR with local permissions and
converted these consumers to use the MR associated with the PD
rather then device->local_dma_lkey.
ConnectIB has some known issues with memory registration
using the local_dma_lkey (SEND, RDMA, RECV seems to work ok).
Thus don't expose support for it (remove device->local_dma_lkey
setting), and take advantage of the above commit such that no regression
is introduced to working systems.
The local_dma_lkey support will be restored in CX4 depending on FW
capability query.

of_phy_find_device() increments the phy struct device refcount, which
we need to properly balance. Add code to network drivers using this
function to ensure that the struct device refcount is correctly
balanced.
For xgene, looking back in the history, we should be able to use
of_phy_connect() with a zero flags argument for the DT case as this is
how the driver used to operate prior to de7b5b3d790a ("net: eth: xgene:
change APM X-Gene SoC platform ethernet to support ACPI").
This leaves the Cavium Thunder BGX unfixed; fixing this driver is a
complicated task, one which the maintainers need to be involved with.

Take a refcount on the phy struct device when the phy device is attached
to a network device, and drop it after it's detached. This ensures that
a refcount is held on the phy device while the device is being used by
a network device, thereby preventing the phy_device from being
unexpectedly kfree()'d by phy_device_release().

Re-implement the mdiobus module refcounting to ensure that we actually
ensure that the mdiobus module code does not go away while we might call
into it.
The old scheme using bus->dev.driver was buggy, because bus->dev is a
class device which never has a struct device_driver associated with it,
and hence the associated code trying to obtain a refcount did nothing
useful.
Instead, take the approach that other subsystems do: pass the module
when calling mdiobus_register(), and record that in the mii_bus struct.
When we need to increment the module use count in the phy code, use
this stored pointer. When the phy is deteched, drop the module
refcount, remembering that the phy device might go away at that point.
This doesn't stop the mii_bus going away while there are in-use phys -
it merely stops the underlying code vanishing.

...
while ((dev = class_dev_iter_next(&iter))) {

It is mostly a non issue, unless we want to mix different NIC
in a host, and want consistent hashing among all of them, ie
if they all use the boot time generated rss key, or if some application
is choosing specific tuple(s) so that incoming traffic lands into known
rx queue(s).

The device is set as wakeup capable using proper wakeup API but the
driver misuses IRQF_NO_SUSPEND to set the interrupt as wakeup source
which is incorrect.
This patch removes the use of IRQF_NO_SUSPEND flags replacing it with
enable_irq_wake instead.

wcn3620 prima firmware exposes more capabilities than known about
in the mainline driver, they're reported as "unknown" at probe.
This adds the extra capabilities so they can at least be reported
correctly.

wcn3620 has a new message structure for the reply to some hal
commands. This patch adds the struct and helper routine that
uses it if the chip is wcn3620, or falls back to the old
helper routine.
We don't know what to do with the candidate list he sends back,
but we can at least accept and ignore it nicely instead of dying.

The low 16 bits of the 'opts1' field in the TX descriptor are supposed
to still contain the buffer length when the descriptor is handed back to
us. In practice, at least on my hardware, they don't. So stash the
original value of the opts1 field and get the length to unmap from
there.
There are other ways we could have worked out the length, but I actually
want a stash of the opts1 field anyway so that I can dump it alongside
the contents of the descriptor ring when we suffer a TX timeout.
