2015-03-03at86rf230: restore trx len when neededAlexander Aring1-4/+8
In the most cases the spi messages has a length of two. Currently we always set the the len field to two before transmit a spi message. In cases for read out/write in the frame buffer we need another len. This patch use trx len two as default. For the frame buffer cases we restore the trx len to two on success and failure. This will reduce the len setting of two when it's already two. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2015-03-03at86rf230: remove multiple dereferencing for ctxAlexander Aring1-13/+12
This patch cleanups the referencing for the state change context variable. The state change context should only set once and this is by initial a state change. This patch will use the initial state change variable in the complete handler of the state change by using the ctx context which should be always the same like the initial state change context.

2015-03-03at86rf230: add transmit retry supportAlexander Aring1-3/+21
This patch introduce a transmit retry handling into at86rf230 transmit path. Current behaviour is to wait the normal receive time if we want to go into STATE_TX_ON when the transceiver is in STATE_BUSY_RX_AACK which indicates that a frame is currently receiving. A non force state change will not interrupt the the receiving state. The current behaviour is that after the normal receive time we will start a force change into STATE_TX_ON. With this patch we do seven retries to go into STATE_TX_ON without forcing. After we hit the AT86RF2XX_MAX_TX_RETRIES we will start the force state change. This is a polling like method to go into STATE_TX_ON in times of maximum receiving time. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2015-03-03Bluetooth: btusb: Add support for QCA ROME chipset familyKim, Ben Young Tae1-0/+254
This patch supports ROME Bluetooth family from Qualcomm Atheros, e.g. QCA61x4 or QCA6574. New chipset have similar firmware downloading sequences to previous chipset from Atheros, however, it doesn't support vid/pid switching after downloading the patch so that firmware needs to be handled by btusb module directly. ROME chipset can be differentiated from previous version by reading ROM version.

2015-03-02pppoe: Use workqueue to die properly when a PADT is receivedSimon Farnsworth1-1/+16
When a PADT frame is received, the socket may not be in a good state to close down the PPP interface. The current implementation handles this by simply blocking all further PPP traffic, and hoping that the lack of traffic will trigger the user to investigate. Use schedule_work to get to a process context from which we clear down the PPP interface, in a fashion analogous to hangup on a TTY-based PPP interface. This causes pppd to disconnect immediately, and allows tools to take immediate corrective action. Note that pppd's rp_pppoe.so plugin has code in it to disable the session when it disconnects; however, as a consequence of this patch, the session is already disabled before rp_pppoe.so is asked to disable the session. The result is a harmless error message: Failed to disconnect PPPoE socket: 114 Operation already in progress This message is safe to ignore, as long as the error is 114 Operation already in progress; in that specific case, it means that the PPPoE session has already been disabled before pppd tried to disable it.

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.

2015-02-25net: dsa: bcm_sf2: add HW bridging supportFlorian Fainelli3-1/+171
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.

2015-02-24i40e: Add support for getlink, setlink ndo opsNeerav Parikh6-22/+196
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. Also update the copyright year.

2015-02-24i40e: Implement configfs for NPAR BW configurationGreg Rose4-8/+369
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.

2015-02-24i40e: enable packet split only when IOMMU presentMitch Williams2-2/+7
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.

2015-02-24i40e: Add method to keep track of current rxnfc settingsCarolyn Wyborny2-1/+12
This patch adds a struct to the VSI struct to keep track of rxnfc settings done via ethtool. Without this patch, the device can only list the options available, not the current settings and this is not clear to the user. Without current settings, the available settings never changing looks like a bug. Also update the copyright year.

2015-02-24i40e/i40evf: Use advertised speed settings in ethtool and refactor get_settingsCatherine Sullivan4-124/+173
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.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next 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: David S.
