- Not so sure that minimum MTU number is really what was intended, but
  that's what the math actually makes it out to be, due to max_frame

  comparing new_mtu. (I think 68 was the intended min_mtu value).

====================
add support for impedance control for TI dp83867 phy and fix 2nd ethernet on dra72 rev C evm

Add support for configurable impedance control for TI dp83867
phy via devicetree. More documentation in [1].
CPSW second ethernet is not working, fix it by enabling
impedance configuration on the phy.

Verified the patch on DRA72 Rev C evm, logs at [2]. Also pushed
a branch [3] for others to test.

Changes from v3:
* Fixup change log text and no code changes.

Changes from v2:
* Fixed a typo in dts and driver.

Changes from initial version:
* As per Sekhar's comment, instead of passing impedance values,
  change to max and min impedance from DT
* Adopted phy_read_mmd_indirect() to cunnrent implementation.
* Corrected the phy delay timings to the optimal value.

David S. Miller 3aaf8630bf Merge branch 'mv88e6xxx-interrupt-support'
Andrew Lunn says:

====================
Interrupt support for mv88e6xxx

This patchset add interrupt controller support to the MV88E6xxx.  This
allows access to the interrupts the internal PHY generate. These
interrupts can then be associated to a PHY device in the device tree
and used by the PHY lib, rather than polling.

Since interrupt handling needs to make MDIO bus accesses, threaded
interrupts are used. The phylib needs to request the PHY interrupt
using the threaded IRQ API. This in term allows some simplification to
the code, in that the phylib interrupt handler can directly call
phy_change(), rather than use a work queue. The work queue is however
retained for the phy_mac_interrupt() call, which can be called in hard
interrupt context.

Since RFC v1:

Keep phy_mac_interrupt() callable in hard IRQ context.

The fix to trigger the phy state machine transitions on interrupts has
already been submitted, so is dropped from here.

Added back shared interrupts support.

The PHY interrupts are now handled in a threaded interrupt handler,
which can sleep. The work queue is no longer needed, phy_change() can

in interrupt context, so keep the work queue, and use a helper to call
phy_change().

The interrupt lines from PHYs maybe connected to I2C bus expanders, or

ila: Cache a route in ILA lwt structure

Add a dst_cache to ila_lwt structure. This holds a cached route for the
translated address. In ila_output we now perform a route lookup after
translation and if possible (destination in original route is full 128
bits) we set the dst_cache. Subsequent calls to ila_output can then use
the cache to avoid the route lookup.

This eliminates the need to set the gateway on ILA routes as previously
was being done. Now we can do somthing like:

./ip route add 3333::2000:0:0:2/128 encap ila 2222:0:0:2 \
    csum-mode neutral-map dev eth0  ## No via needed!

Also, add destroy_state to lwt ops. We need this do destroy the
dst_cache.

- v2
  - Fixed comparisons to fc_dst_len to make comparison against number
    of bits in data structure not bytes.
  - Move destroy_state under build_state (requested by Jiri)
  - Other minor cleanup

Tested:

Running 200 TCP_RR streams:

  Baseline, no ILA

    1730716 tps
    102/170/313 50/90/99% latencies
    88.11 CPU utilization

  Using ILA in both directions

    1680428 tps
    105/176/325 50/90/99% latencies
    88.16 CPU utilization

Tom Herbert 1104d9ba44 lwtunnel: Add destroy state operation
Users of lwt tunnels may set up some secondary state in build_state
function. Add a corresponding destroy_state function to allow users to
clean up state. This destroy state function is called from lwstate_free.
Also, we now free lwstate using kfree_rcu so user can assume structure
is not freed before rcu.

While handling SPQ ramrod completion, there is a possible race
where driver might not read updated fw return code based on
ramrod completion done. This patch ensures that fw return code
is written first and then completion done flag is updated
using appropriate memory barriers.

Yuval Mintz 7eff82b0fc qed: Handle malicious VFs events
Malicious VFs might be caught in several different methods:
  - Misusing their bar permission and being blocked by hardware.
  - Misusing their fastpath logic and being blocked by firmware.
  - Misusing their interaction with their PF via hw-channel,
    and being blocked by PF driver.

On the first two items, firmware would indicate to driver that
the VF is to be considered malicious, but would sometime still
allow the VF to communicate with the PF [depending on the exact
nature of the malicious activity done by the VF].
The current existing logic on the PF side lacks handling of such events,
and might allow the PF to perform some incorrect configuration on behalf
of a VF that was previously indicated as malicious.

The new scheme is simple -
Once the PF determines a VF is malicious it would:
 a. Ignore any further requests on behalf of the VF-driver.
 b. Prevent any configurations initiated by the hyperuser for
    the malicious VF, as firmware isn't willing to serve such.

The malicious indication would be cleared upon the VF flr,
after which it would become usable once again.

Yuval Mintz c59f5291fd qed: Allow chance for fast ramrod completions
Whenever a ramrod is being sent for some device configuration,
the driver is going to sleep at least 5ms between each iteration
of polling on the completion of the ramrod.

However, in almost every configuration scenario the firmware
would be able to comply and complete the ramrod in a manner of
several usecs. This is especially important in cases where there
might be a lot of sequential configurations applying to the hardware
[e.g., RoCE], in which case the existing scheme might cause some
visible user delays.

This patch changes the completion scheme - instead of immediately
starting to sleep for a 'long' period, allow the device to quickly
poll on the first iteration after a couple of usecs.

While we're at it - relax a hard-coded limitation that limits each
interface into using at most 15 unicast MAC addresses before turning
promiscuous. Instead utilize the HW resources to their limit.
