2015-03-02bcma: add helpers bringing PCIe hosted bus up / downRafał Miłecki5-24/+38
Bringing PCIe hosted bus up requires operating on host-related core. Since we plan to support PCIe Gen 2 devices we should provide a helper picking the correct one (PCIE or PCIE2). Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

Boot loader reports MAC address and detects radio chip connected. Driver loads firmware only when bringing up interface.

2015-02-27mwifiex: more_task flag for main_processShengzhen Li2-7/+10
This patch handles a corner case where TX packet would remain in driver queue till next packet comes in. Here is sequence: 1. TX packet is queued via hard_start_xmit and main_work is queued 2. SDIO interrupt comes in which directly call mwifiex_main_process. This starts executing main superloop. 3. Now work from step1 is scheduled but at first check itself it sees mwifiex_processing is set and exits. 4. Now if superloop from step2 has passed TX processing part of superloop this packet would remain in queue until next packet/command/SDIO interrupt arrives and queues main_work. This patch fixes this corner case by defining more_task flag which is set when mwifiex_processing is found to be true. At end of superloop we again check if more_task flag is set and if set, execute superloop again.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next 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>
2015-02-26net: 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.

2015-02-25i40e: 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.

2015-02-25i40e: 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.

2015-02-25i40evf: allow enabling of debug prints via ethtoolAshish Shah1-2/+4
Copy setting from ethtool to the HW specific struct to actually enable prints. Change print from i40e to i40evf to differentiate drivers in bare metal scenarios. Also update the copyright year.
