The power save state of MCI has to be disabled when enabling WoW sleep, check this properly. ar9003_mci_state() doesn't handle MCI_STATE_GET_WLAN_PS_STATE right now, but this will be done later when proper support for MCI/PS is added. Signed-off-by:

Jeff Kirsher says: ==================== 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. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Florian Fainelli says: ==================== 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. ==================== Signed-off-by: -

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.

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. Signed-off-by:

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.

Neerav Parikh authored
Add 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 case of a PF VSI and not available for any other VSI type. By default the i40e driver inserts a bridge as part of the bring-up when a FDIR type VSI and/or a FCoE VSI is created. This bridge is created in VEB mode by default i.e. after creating the bridge using "Add VEB" AQ command the loopback for the PF's default VSI is enabled. The patch adds capability where all the VSIs created as downlink to the bridge inherits the loopback property and enables loopback only if the uplink bridge is operating in VEB mode. Hence, there is no need to explicitly enable loopback as part of allocating resources for SR-IOV VFs and call to do that has been removed. In case a user-request is made either via "bridge" utility or using the bridge netlink interface that requires to change the hardware bridge mode then that would require a PF reset and rebuild of the switch hierarchy.

Add configfs controls to get, set and commit NPAR BW configurations. We export three controls: min_bw - Can take a value from 0 to 100 inclusive max_bw - Can take a value from 1 to 100 inclusive commit - A write-only control that accepts only a value of 1 and will cause the BW settings to be permanently committed to NVM so that they are persistent across power cycles and system resets The BW values are relative and are expressed as percentages. For more information on the interpretation of the BW settings see the Dell specifications for NPAR. Also update the copyright year. Change-ID: Id7496ca65630b5037e32ba6a5a748fbc1632881b Signed-off-by:

When an IOMMU is in use, the packet split receive path shows a distinct advantage over the single-buffer path because it minimizes DMA mapping and unmapping. However, this is not an advantage for systems with no IOMMU. At init time, check to see if an IOMMU is enabled and enable packet split receives.

Add a requested speed variable to the link_status struct to store the last speeds we requested from the firmware (the speeds the FW will be advertising with if autoneg is enabled). Use the advertised speed settings in get_settings in ethtool now that we have it. Also set the requested speed settings in set_settings in ethtool as they are requested and initialize them in probe based on what the firmware remembers as the last requested speeds. To accommodate some longer lines in this new code, and improve readability I have added two functions i40e_get_settings_link_up and i40e_get_settings_link_down which get_settings now calls first. It then does all of the settings that happen regardless of link state. Some PHY types that supported the same settings were also combined. Also update the copyright year.

The Churn Detection machines detect the situation where a port is operable, but the Actor and Partner have not attached the link to an Aggregator and brought the link into operation within a bound time period. Under normal operation of the LACP, agreement between Actor and Partner should be reached very rapidly. Continued failure to reach agreement can be symptomatic of device failure.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-02-23 This series contains updates to e1000e, igbvf, i40e and i40evf. David adds support for i219 devices to the e1000e driver. Jeff (me) provides two patches to cleanup igbvf, first cleans up the whitespace issues found and the second cleans up the usage of msleep(), min() and max() with usleep_range(), min_t() and max_t() respectively. Kamil updates the shadow RAM read/write functions by refactoring them to prepare for future work. Shannon renames the debugfs command "clear_stats pf" to clear_stats port" to clarify what the function really does. Mitch refactors the receive routine, by splitting the receive hot path code into two, one for packet split and one for single buffer, which improves receive performance. Disables NAPI polling sooner when closing the interface to fix an occasional panic during close which was caused by the driver trying to delete and clean rings at the same time. Also refactors reset for i40evf, since a recent change to the shutdown flow messed up the reset flow. Since i40evf_down() now holds the critical section lock, we cannot call it from the reset handler, which also holds the lock. Nicholas restricts the virtual channel opcodes should remain consistent between updates to the opcode enum. Neerav converts the VSI connection type to use a #define instead of using a magic number. Anjali updates the registers file to remove registers no longer available. Also fixes the EMPR interrupt handling, so that we won't trigger another EMPR when we receive an EMPR event. Catherine cleans up the variable an_enable since it was set and never used. Greg fixes the netdev op that allows the operator to turn MAC/VLAN spoof checking on and off so that it includes the flag for VLAN spoof checking. v2: Updated patch #10 in the series to use test_and_clear_bit() as suggested by Sergei Shtylyov ==================== Signed-off-by: -
