net/smc: get rid of unsafe_global_rkey

The smc code uses the unsafe_global_rkey, exposing all memory for

nfp: extend firmware request logic

We have been pondering for some time how to support loading different
application firmwares onto NFP.  We want to support both users selecting
one of the firmware images provided by Netronome (which are optimized
for different use cases each) as well as firmware images created  by
users themselves or other companies.

In the end we decided to go with the simplest solution - depending on
the right firmware image being placed in /lib/firmware.  This vastly
simplifies driver logic and also doesn't require any new API.

Different NICs on one system may want to run different applications
therefore we first try to load firmware specific to the device (by
serial number of PCI slot) and if not present try the device model
based name we have been using so far.
====================

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.

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.

10GbE Intel Wired LAN Driver Updates 2017-07-25

This series contains updates to ixgbe only.

Tony provides all of the changes in the series, starting with adding a
check to ensure that adding a MAC filter was successful, before setting the
MACVLAN.  In order to receive notifications of link configurations of the
external PHY and support the configuration of the internal iXFI link on
X552 devices, Tony enables LASI interrupts.  Update the iXFI driver code
flow, since the MAC register NW_MNG_IF_SEL fields have been redefined for
X553 devices, so add MAC checks for iXFI flows.  Added additional checks
for flow control autonegotiation, since it is not support for X553 fiber
 and XFI devices.

v2: removed unnecessary parens noticed by David Miller in patch 6 of the
    series.
v3: dropped patch 6 of the original series, while we work out a more
    generic solution for malicious driver detection (MDD) support.
v4: updated patch 1 of the series with the comments from Joe Perches which
    were:
      - switched logic to return on error
      - return 0 on success
      - declare retval as an integer
