bcmgenet_mii_init() has an error path which is strictly identical to the
unwinding that bcmgenet_mii_exit() does, so have bcmgenet_mii_init()
utilize bcmgenet_mii_exit() for that.

Update the GENET driver to register an UniMAC MDIO bus controller for
the GENET internal MDIO bus, update the platform data code to attach the
PHY to the correct MDIO bus controller.
The Device Tree portion of the code is mostly left unmodified since the
lookup/binding is done via phandles and Device Tree nodes which are much
more flexible in locating and binding PHYs to their respective MDIO bus
controllers.

The FEC Receive Control Register has a 14 bit field indicating the
longest frame that may be received. It is being set to 1522. Frames
longer than this are discarded, but counted as being in error.
When using DSA, frames from the switch has an additional header,
either 4 or 8 bytes if a Marvell switch is used. Thus a full MTU frame
of 1522 bytes received by the switch on a port becomes 1530 bytes when
passed to the host via the FEC interface.
Change the maximum receive size to 2048 - 64, where 64 is the maximum
rx_alignment applied on the receive buffer for AVB capable FEC
cores. Use this value also for the maximum receive buffer size. The
driver is already allocating a receive SKB of 2048 bytes, so this
change should not have any significant effects.
Tested on imx51, imx6, vf610.

If the PHY is missing but expected, e.g. because of a typ0 in the dt
file, it is not possible to open the interface. ip link returns:
RTNETLINK answers: No such device
It is not very obvious what the problem is. Add a netdev_err() in this
case to make it easier to debug the issue.

For SGMII/RGMII/QSGMII interfaces when physical link goes down
while traffic is high is resulting in underflow condition being set
on that specific BGX's LMAC. Which assets a backpresure and VNIC stops
transmitting packets.
This is due to BGX being disabled in link status change callback while
packet is in transit. This patch fixes this issue by not disabling BGX
but instead just disables packet Rx and Tx.

request_firmware() will fallback to user space helper and may cause
long delays when driver is loaded if udev doesn't correctly handle
FW requests. Since we never really made use of the user space
helper functionality switch to the simpler request_firmware_direct()
call. The side effect of this change is that no warning will be
printed when the FW image does not exists. To help users figure
out which FW file is missing print a info message when we request
each file.

We generally look up firmware by card type, but that doesn't allow
users who have more than one card of the same type in their system
to select firmware per adapter.
Unfortunately user space firmware helper seems fraught with
difficulties and to be on its way out. In particular support for
handling firmware uevents have been dropped from systemd and most
distributions don't enable the FW fallback by default any more.
To allow users selecting firmware for a particular device look up
firmware names by serial and pci_name(). Use the direct lookup to
disable generating uevents when enabled in Kconfig and not print
any warnings to logs if adapter-specific files are missing. Users
can place in /lib/firmware/netronome files named:
pci-${pci_name}.nffw
serial-${serial}.nffw
to target a specific card. E.g.:
pci-0000:04:00.0.nffw
pci-0000:82:00.0.nffw
serial-00-aa-bb-11-22-33-10-ff.nffw
We use the full serial number including the interface id, as it
appears in lspci output (bytes separated by '-').

We use a hack to defer probe when firmware was not pre-loaded
or found on disk. This helps in case users forgot to include
firmware in initramfs, the driver will most likely get another
shot at probing after real root is mounted.
This is not for what EPROBE_DEFER is supposed to be used, and
when FW is completely missing every time new device is probed
NFP will reprobe spamming kernel logs.
Remove this hack, users will now have to make sure the right
firmware image is present in initramfs if nfp.ko is placed
there or built in.

When adding ethtool steering rule with action DISCARD we wrongly
pass a NULL dest with dest_num 1 to mlx5_add_flow_rules().
What this error seems to have caused is sending VPORT 0
(MLX5_FLOW_DESTINATION_TYPE_VPORT) as the fte dest instead of no dests.
We have fte action correctly set to DROP so it might been ignored
anyways.
To reproduce use:

On interface remove, the clean-up was done incorrectly causing
an error in the log:
"SET_FLOW_TABLE_ROOT(0x92f) op_mod(0x0) failed...syndrome (0x7e9f14)"
This was caused by the following flow:
-ndo_uninit:
Move QP state to RST (this disconnects the QP from FT),
the QP cannot be attached to any FT unless it is in RTS.
-mlx5_rdma_netdev_free:
cleanup_rx: Destroy FT
cleanup_tx: Destroy QP and remove QPN from FT
This caused a problem when destroying current FT we tried to
re-attach the QP to the next FT which is not needed.
The correct flow is:
-mlx5_rdma_netdev_free:
cleanup_rx: remove QPN from FT & Destroy FT
cleanup_tx: Destroy QP

The tx_enabled lag event field is used to determine whether a slave is
active.
Current logic uses this value only if the mode is active-backup.
However, LACP mode, although considered a load balancing mode, can mark
a slave as inactive in certain situations (e.g., LACP timeout).
This fix takes the tx_enabled value into account when remapping, with
no respect to the LAG mode (this should not affect the behavior in XOR
mode, since in this mode both slaves are marked as active).

====================
40GbE Intel Wired LAN Driver Updates 2017-07-25
This series contains updates to i40e and i40evf only.
Gustavo Silva fixes a variable assignment, where the incorrect variable
was being used to store the error parameter.
Carolyn provides a fix for a problem found in systems when entering S4
state, by ensuring that the misc vector's IRQ is disabled as well.
Jake removes the single-threaded restriction on the module workqueue,
which was causing issues with events such as CORER. Does some future
proofing, by changing how the driver displays the UDP tunnel type.
Paul adds a retry in releasing resources if the admin queue times out
during the first attempt to release the resources.
Jesse fixes up references to 32bit timspec, since there are a small set
of errors on 32 bit, so we need to be using the right calls for dealing
with timespec64 variables. Cleaned up code indentation and corrected
an "if" conditional check, as well as making the code flow more clear.
Cast or changed the types to remove warnings for comparing signed and
unsigned types. Adds missing includes in i40evf, which were being used
but were not being directly included.
Daniel Borkmann fixes i40e to fill the XDP prog_id with the id just like
other XDP enabled drivers, so that on dump we can retrieve the attached
program based on the id and dump BPF insns, opcodes, etc back to user
space.
Tushar Dave adds le32_to_cpu while evaluating the hardware descriptor
fields, since they are in little-endian format. Also removed
unnecessary "__packed" to a couple of i40evf structures.
Stefan Assmann fixes an issue when an administratively set MAC was set
and should now be switched back to 00:00:00:00:00:00, the pf_set_mac
flag is not being toggled back to false.

The i40e driver attempts to display the UDP tunnel name by doing a check
against the type, where for non-zero types we use "vxlan" and for zero
type we use "geneve". This is not future proof, because if new tunnel
types get added, we'll incorrectly label them. It also depends on the
value of UDP_TUNNEL_TYPE_GENEVE == 0, which is brittle.
Instead, replace this with a function that can return a constant string
depending on the type. For now we'll use "unknown" for types we don't
know about, and we can expand this in the future if new types get added.
