      ath9k: Set keep awake timer · 0d35024c
      由 Sujith Manoharan 提交于 
      When MCI is enabled and WoW sleep is enabled,
make sure that the RTC keep awake timer is set
with the required value. This is also required
when the AR_WA is programmed.

      ath9k: Fix descriptors for keep-alive frame · 2a0eef1a
      由 Sujith Manoharan 提交于 
      Along with AR9462, AR9565 also has an extra field
in the TX descriptor which needs to be zeroed out
for the keep alive frame. This makes the earlier
REG_WRITE redundant, so it can be removed.

Intel Wired LAN Driver Updates 2015-02-24

This series contains updates to i40e and i40evf only, which bumps their
versions to i40e 1.2.9 and i40evf 1.2.3.

Paul fixes i40e_debug_aq() for big endian machines by adding the
appropriate LExx_TO_CPU wrappers.

Catherine adds a requested speed variable to the link_status to store the
last speeds we requested from the firmware and use the advertised speed
settings in get_settings in ethtool now that we have it.  Due to the
new code addition, she also refactors get_settings to improve readability
and to accommodate some of the longer lines of code by adding two
functions i40e_get_settings_link_up() and i40e_get_settings_link_down().

Carolyn adds a struct to the VSI struct to keep track of RXNFC settings
done via ethtool.  Adds more information to the interrupt vector
names, specifically to the VF misc vector name so that we can distinguish
between all the interrupts.

Ashish enables the i40evf driver to enable debug prints via ethtool.

Mitch updates i40e to enable packet split only when IOMMU is in use,
since it shows a distinct advantage over the single-buffer path
because it minimizes DMA mapping and unmapping.  Also adds the receive
routine in use to the features log message to be able to print the
receive packet split status.

Greg adds the ability to get, set and commit permanently the NPAR
partition BW configuration through configfs.  Enables an application
to query the i40e driver's private flags to get the status of NPAR
enablement via ethtool.

Neerav adds support for bridge offload ndo_ops getlink and setlink
to enable bridge hardware mode as per the mode set via IFLA_BRIDGE_MODE.
The support is only enabled in the case of a PF VSI and not available for
any other VSI type.

Kevin fixes i40e by ensuring the BUF and FLAG_RD flags are set for
indirect admin queue command.

Vasu updates the driver to setup FCoE netdev device type as "fcoe", so that
it shows up in sysfs as FCoE device.

      net: dsa: Introduce dsa_is_port_initialized · d79d2107
      由 Guenter Roeck 提交于 
      To avoid race conditions when using the ds->ports[] array,
we need to check if the accessed port has been initialized.
Introduce and use helper function dsa_is_port_initialized
for that purpose and use it where needed.

net: dsa: integration with SWITCHDEV for HW bridging

This patch set provides the DSA and SWITCHDEV integration bits together and
modifies the bcm_sf2 driver accordingly such that it works properly with HW
bridging.

Changes in v3:

- add back the null pointer check in dsa_slave_br_port_mask from Guenter
- slightly rework patch 1 commit message not to mention the function name
  we add in patch 2

Changes in v2:

- avoid a race condition in how DSA network devices are created, patch from
  Guenter Roeck
- provide a consistent and work STP state once a port leaves the bridge
- retain a bridge device pointer to properly flag port/bridge membership
- properly flush the ARL (Address Resolution Logic) in bcm_sf2.c
- properly retain port membership when individually bringing devices up/down
  while they are members of a bridge

We discussed on the mailing-list the possibility of standardizing a "fdb_flush"
operation for DSA switch drivers, looking at the Marvell and Broadcom switches,
I am not convinced this is practical or diserable as the terminologies vary
here, but there is nothing preventing us from doing it later.

Many thanks to Guenter and Andrew for both testing and providing feedback.

      net: dsa: bcm_sf2: add HW bridging support · 12f460f2
      由 Florian Fainelli 提交于 
      Implement the bridge join, leave and set_stp callbacks by making that
we do the following:

- when a port joins the bridge, all existing ports in the bridge get
  their VLAN control register updated with that joining port
- the joining port is including all existing bridge ports in its own
  VLAN control register

The leave operation is fairly similar, special care must be taken to
make sure that port leaving the bridging is not removing itself from its
own VLAN control register.

Since the various BR_* states apply directly to our HW semantics, we
just need to translate these constants into their corresponding HW
settings, and voila!

We make sure to trigger a fast-ageing process for ports that are
joining/leaving the bridge and transition from incompatible states, this
is equivalent to triggering an ARL flush for that port.

      net: dsa: integrate with SWITCHDEV for HW bridging · b73adef6
      由 Florian Fainelli 提交于 
      In order to support bridging offloads in DSA switch drivers, select
NET_SWITCHDEV to get access to the port_stp_update and parent_get_id
NDOs that we are required to implement.

To facilitate the integratation at the DSA driver level, we implement 3
types of operations:

- port_join_bridge
- port_leave_bridge
- port_stp_update

DSA will resolve which switch ports that are currently bridge port
members as some Switch hardware/drivers need to know about that to limit
the register programming to just the relevant registers (especially for
slow MDIO buses).

We also take care of setting the correct STP state when slave network
devices are brought up/down while being bridge members.

Finally, when a port is leaving the bridge, we make sure we set in
BR_STATE_FORWARDING state, otherwise the bridge layer would leave it
disabled as a result of having left the bridge.

      net: dsa: Ensure that port array elements are initialized before being used · d87d6f44
      由 Guenter Roeck 提交于 
      A network device notifier can be called for one or more of the created
slave devices before all slave devices have been registered. This can
result in a mismatch between ds->phys_port_mask and the registered devices
by the time the call is made, and it can result in a slave device being
added to a bridge before its entry in ds->ports[] has been initialized.

Rework the initialization code to initialize entries in ds->ports[] in
dsa_slave_create. With this change, dsa_slave_create no longer needs
to return slave_dev but can return an error code instead.
