SFP updates

Included in this series are a further few updates for SFP support:

- Adding support for Fiberstore's non-standard BiDi modules operating
  at 1310nm/1550nm wavelengths rather than the 1000BASE-BX standard of
  1310nm/1490nm.
- Adding support for negotiating the PHY interface mode with the MAC,
  so that modules supporting faster speeds and Gigabit ethernet work
  with Gigabit-only MACs.
- Adding support for high power (>1W) SFP modules.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

This patch is the result of work by both Jon Nettleton and Russell King.
Jon wrote the original patch, adding support for SFP modules which
require a power level greater than '1'.

Russell's changes:
- Fix the power levels for big-endian, and make the code flow better.
- Convert to use device_property_read_u8()
- Warn for power levels exceeding host level
  SFF-8431 says:

  "To avoid exceeding system power supply limits and cooling capacity,
   all modules at power up by default shall operate with up to 1.0 W.
   Hosts supporting Power Level II or III operation may enable a Power
   Level II or III module through the 2-wire interface. Power Level II
   or III modules shall assert the power level declaration bit of
   SFF-8472."

  Print a warning for modules that exceed the host power level, and
  leave them operating in power level 1.

- Fix i2c write
  The first byte of any write after the bus address is always the
  device address.  In order to write a value to device D, address I,
  value V, we need to generate on the bus:

    S DDDDDDDD A IIIIIIII A VVVVVVVV A P

  where S = start, R = restart, A = ack, P = stop.  Splitting this
  as two:

    S DDDDDDDD A IIIIIIII A R DDDDDDDD A VVVVVVVV A P

  results in the device's address register being written first by I
  and then by V - the addressed register within the device is not
  written.

- Avoid power mode switching if 0xa2 is not implemented
  Some modules indicate that they support power level II or power level
  III, but do not implement address 0xa2, meaning that the bit to set
  them to high power mode is not accessible.

  These modules appear to have the sff8472_compliance field set to zero,
  and also do not implement diagnostics.  Detect this, but also ensure
  that the module does not require the address switching mode, which we
  do not implement.

- Use mW for power level rather than power level number.

- Fix high power mode transition
  We must not switch to SFP_MOD_PRESENT state until we have finished
  initialising, because the remaining state machines check for that
  state.  Add SFP_MOD_HPOWER as an intermediate state.

- Use definition for I2C register address rather than constant.

mlx5-update-2018-02-23 (IB representors)

From: Mark Bloch <markb@mellanox.com>
=========
Add IB representor when in switchdev mode

The following series adds support for an IB (RAW Ethernet only) device
representor which is created when the user switches to switchdev mode.

Today when switching to switchdev mode the only representors which are
created are net devices. Each netdev is a representor of a virtual
function and any data sent via the representor is received on the virtual
function, and any data sent via the virtual function is received by the
representor.

For the mlx5 driver the main use of this functionality is to be able to
use Open vSwitch on the hypervisor in order to manage/control traffic
from/to the virtual functions. Open vSwitch can also work with  DPDK
devices and not just net devices, this series exposes an IB device, which
Mellanox PMD driver uses, which then can be used by Open vSwitch DPDK.

An IB device representor exposes only RAW Ethernet QP capabilities and
the ability to create flow rules to direct traffic to its RX queues. The
state of the IB device (ACTIVE/DOWN etc..) is based on the state of the
corresponding net device representor. No other RDMA/RoCE functionality is
currently supported and no GID table is exposed.

mlxsw: Offloading encapsulated SPAN

Petr says:

This patch series introduces support for mirroring with GRE
encapsulation. It offloads tc action mirred mirror from a mlxsw port to
either a gretap or an ip6gretap netdevice.

Spectrum hardware needs to know all the details of the requested
encapsulation: source and destination MAC and IP addresses, details of
VLAN tagging, etc. The only variables are the encapsulated packet
itself, and TOS field, which may be inherited. To that end, mlxsw driver
resolves the route that encapsulated packets would take, queries the
corresponding neighbor, and with that configuration in hand, configures
the mirroring in the hardware.

The driver also hooks into event handlers for netdevice changes, FIB and
neighbor events, and reconsiders the configuration on each such change.
When the new configuration differs from the currently-offloaded one, the
existing offload is removed and replaced with a new one.

It is possible to mirror to {ip6,}gretap from a matchall rule as well as
from a flower match.

** Note that with this patch set, mlxsw build depends on NET_IPGRE and
   IPV6_GRE.

Current limitations:

- There has to be a route that directs packets to an mlxsw port. We
  intend to extend the logic to support other netdevice types in the
  future, but the eventual egress netdevice will have to be an mlxsw
  port in any case.

- Offload reconfiguration due to changes in netdevice configuration
  creates a window of time where packets are not mirrored. Under some
  circumstances this can be prevented by configuring an unused port
  analyzer and migrating mirrors over to that. However that's currently
  not implemented.

- Remote address of a tunnel device needs to be set, there may not be a
  GRE key, checksumming or sequence numbers, and TTL needs to be fixed
  (non-inherit). These are hard requirements imposed by the underlying
  hardware.

- TOS of a tunnel device needs to be "inherit". The hardware supports a
  fixed TOS, but that's currently not implemented.

The series start with two patches, #1 and #2, that publish one function
and add support for querying IPv6 tunnel parameters.

In patches #3 and #4, we introduce helpers to GRE and tunneling code
that we will use later in the patchset from the SPAN code.

Patches #5 and #6 introduce support for encapsulated SPAN in reg.h.

The following seven patches, #7-#13, then prepare the SPAN codebase for
introduction of mirroring to netdevices that don't correspond to front
panel ports.

Then #14 and #15 pull all this together to implement mirroring to
{ip6,}gretap netdevices.

When a user requests mirror from a mlxsw physical port (possibly based

request to a particular physical port that the mirrored packets will
egress through, and a suite of configuration keys (importantly, IP and

to simulate the decisions made by the system for packets passing through

Currently the only mirror action supported by mlxsw is mirror to another
mlxsw physical port. Correspondingly, span_entry, which tracks each
mlxsw mirror in the system, currently holds a u8 number of the
destination port.

To extend this system to mirror to gretap and ip6gretap netdevices, have
struct mlxsw_sp_span_entry actually hold the destination netdevice
itself.

This change then trickles down in obvious manner to SPAN module API and
mirror-related interfaces in struct mlxsw_afa_ops.

ibmvnic: Miscellaneous driver fixes and enhancements

There is not a general theme to this patch set other than that it
fixes a few issues with the ibmvnic driver. I will just give a quick

"ibmvnic: Fix TX descriptor tracking again" resolves a race condition
introduced in an earlier fix to track outstanding transmit descriptors.
This condition can throw off the tracking counter to the point that
a transmit queue will halt forever.

"ibmvnic: Allocate statistics buffers during probe" allocates queue
statistics buffers on device probe to avoid a crash when accessing
statistics of an unopened interface.

"ibmvnic: Harden TX/RX pool cleaning" includes additional checks to
avoid a bad access when cleaning RX and TX buffer pools during a device
reset.

"ibmvnic: Report queue stops and restarts as debug output" changes TX
queue state notifications from informational to debug messages. This
information is not necessarily useful to a user and under load can result
in a lot of log output.

"ibmvnic: Do not attempt to login if RX or TX queues are not allocated"
checks that device queues have been allocated successfully before
attempting device login. This resolves a panic that could occur if a
user attempted to configure a device after a failed reset.

Thanks for your attention.

Make dwmac4_release_tx_desc() clear all descriptor fields, not just
TDES2 and TDES3.

I'm suspecting that TDES0 and TDES1 wasn't cleared because the DMA
engine uses them to store the tx hardware timestamp (if PTP is enabled).

However, stmmac_tx_clean() calls stmmac_get_tx_hwtstamp(), which reads
and saves the timestamp, before it calls release_tx_desc(), so this
is not an issue.

stmmac_xmit() and stmmac_tso_xmit() both always overwrite TDES0,
however, stmmac_tso_xmit() sometimes sets TDES1, and since neither
stmmac_xmit() nor stmmac_tso_xmit() explicitly clears TDES1, both
functions might reuse a DMA descriptor with old TDES1 data.

I haven't observed any misbehavior even though TDES1 sometimes
point to an old skb, however, explicitly clearing both TDES0 and TDES1
in dwmac4_release_tx_desc() minimizes the chances of undefined behavior.
