====================
Intel Wired LAN Driver Updates 2014-08-27

This series contains updates to i40e and i40evf.

Carolyn provides two patches, first changes the wording of the flow
director add/remove and asynchronous failure messages to include the
fd_id to try and add some way to track the operations on a given fd_id.
Second adds a check during handle_link_event for unqualified modules
when link is down and there is a module plugged in.

Anjali provides four patches to i40e/i40evf.  First update flow director
messages so that a user can tell if a filter was added or deleted.  Then
updates the ATR policy to not auto-disable ATR when we have errors in
programming.  The disabling of ATR when we got programming errors was
buggy and was still adding new rules and causing continuous errors.
With this policy change, we flush instead when we see too many errors.
In addition she adds a flow director flush counter to ethtool to help
know how many times the interface had to flush and replay the flow
director filter table.  Updates the driver to ignores a driver
perceived transmit hang if the number of descriptors pending is less
than 4, and instead log a stat when this situation happens.  This is
because the queue progresses forward and the stack never experiences
a real hang in these situations.

Shannon provides three patches for i40e/i40evf, first enables the
l2tsel bit on receive queue contexts that are assigned to VFs so that
the VF can get the stripped VLAN tag.  Then adds a max buffer size
parameter to the print helper to be sure the code knows when to stop.
Lastly, remove the complaint when removing the default MAC VLAN filter.
This was because old firmware had an incorrect MAC VLAN filter that
needed to be replaced at startup, and now newer firmware does not have
this problem.  So now we only add the new filter if the removal
succeeded and no need to complain if the removal fails.

Ashish provides a change to vsi->num_queue_pairs to equal the number
that is configured by the VF.  This limits the number of queues that
are enabled/disabled and fixes the mismatch case for when a VF
configures fewer queues than is allocated to it by the PF.

      When xmit_more mode is being used and the ring is about to
become full or the stack has stopped the ring, enforce a tail
pointer write to the hw. Otherwise, we could risk a TX hang.

Code suggested by Alexander Duyck.

Broadcom BCM7xxx PHY updates for new entries

Another week, another set of updates for the Broadcom BCM7xxx PHY driver.  This
patch set cleanups the existing definitions, adds a macro to ease the addition
of future chips, and finally add two new SoCs to the list of supported chips.

Resending since the first patch did not make it to the list, sorry about that.

Changes in v2:
- rephrased commit message for patch 1 to make it pass majordomo
  capital triple X was rejected

====================
dsa: Broadcom Starfighter 2 switch support

This patch series adds support for the Broadcom Starfighter 2 (Roboswitch
successor) using the existing DSA infrastructure. This integrated switch
is heavily used in Set Top Box, Cable gateways and DSL gateways products
from Broadcom, and to a larger extent the new ARM-based Wi-Fi routers although
slightly differently.

Changes in v5 are the introduction of ETH_P_XDSA as suggested by Alexander to
help capture applications see this is a multiplexed DSA approach now.

Changes in v4 are the introducing of an indirection level for DSA switch tag
protocols receive and transmit functions.

I intentionnaly did not address one comment from Alexander who suggested to
move port_names and port_dn in a separate structure since that involves
touching arch/arm/ and arch/blackfin/ code which I am not yet comfortable
doing.

Notable changes in v3 is the preliminary patch that reworks the skb->protocol
override helpers for non-Ethertype switch tags, based on feedback from
Alexander Duyck.

The biggest changes from v1 of this patch series are:

- use the new fixed PHY helpers
- improved the switch driver with more complete features (interrupts,
  (RG)MII configuration, memory arrays power down/up, port disabling/enable
  VLAN separation

Future work will focus on bringing the upstream driver in feature parity with
the current downstream driver, including:

- adding Wake-on-LAN support to the switch
- adding suspend/resume callbacks for S2/S3 Power Management modes
- extending the switch register interface to cover BCM5310X SoCs

      Florian Fainelli authored 
      Add support for the Broadcom Starfigther 2 switch chip using a DSA
driver. This switch driver supports the following features:

- configuration of the external switch port interface: MII, RevMII,
  RGMII and RGMII_NO_ID are supported
- support for the per-port MIB counters
- support for link interrupts for special ports (e.g: MoCA)
- powering up/down of switch memories to conserve power when ports are
  unused

Finally, update the compatible property for the DSA core code to match
our switch top-level compatible node.
