2015-07-27bonding: convert num_grat_arp to the new bonding option APINikolay Aleksandrov2-17/+10
num_grat_arp wasn't converted to the new bonding option API, so do this now and remove the specific sysfs store option in order to use the standard one. num_grat_arp is the same as num_unsol_na so add it as an alias with the same option settings. An important difference is the option name which is matched in bond_sysfs_store_option().

2015-07-27net/mlx5e: TX latency optimization to save DMA readsAchiad Shochat5-18/+76
A regular TX WQE execution involves two or more DMA reads - one to fetch the WQE, and another one per WQE gather entry. These DMA reads obviously increase the TX latency. There are two mlx5 mechanisms to bypass these DMA reads: 1) Inline WQE 2) Blue Flame (BF) An inline WQE contains a whole packet, thus saves the DMA read/s of the regular WQE gather entry/s. Inline WQE support was already added in the previous commit. A BF WQE is written directly to the device I/O mapped memory, thus enables saving the DMA read that fetches the WQE. The BF WQE I/O write must be in cache line granularity, thus uses the CPU write combining mechanism. A BF WQE I/O write acts also as a TX doorbell for notifying the device of new TX WQEs. A BF WQE is written to the same I/O mapped address as the regular TX doorbell, thus this address is being mapped twice - once by ioremap() and once by io_mapping_map_wc(). While both mechanisms reduce the TX latency, they both consume more CPU cycles than a regular WQE: - A BF WQE must still be written to host memory, in addition to being written directly to the device I/O mapped memory. - An inline WQE involves copying the SKB data into it. To handle this tradeoff, we introduce here a heuristic algorithm that strives to avoid using these two mechanisms in case the TX queue is being back-pressured by the device, and limit their usage rate otherwise. An inline WQE will always be "Blue Flamed" (written directly to the device I/O mapped memory) while a BF WQE may not be inlined (may contain gather entries). Preliminary testing using netperf UDP_RR shows that the latency goes down from 17.5us to 16.9us, while the message rate (tested with pktgen) stays the same.

2015-07-27net/mlx5e: Allocate DMA coherent memory on reader NUMA nodeSaeed Mahameed5-18/+62
By affinity hints and XPS, each mlx5e channel is assigned a CPU core. Channel DMA coherent memory that is written by the NIC and read by SW (e.g CQ buffer) is allocated on the NUMA node of the CPU core assigned for the channel. Channel DMA coherent memory that is written by SW and read by the NIC (e.g SQ/RQ buffer) is allocated on the NUMA node of the NIC. Doorbell record (written by SW and read by the NIC) is an exception since it is accessed by SW more frequently.

Commit 8d88c6ebb34c ("net: bcmgenet: enable MoCA link state change detection") added a fixed PHY link_update callback for MoCA PHYs when registered using platform_data exclusively, this change is also applicable to systems using Device Tree as their primary configuration interface. In order for this to work, move the link_update assignment into bcmgenet_moca_phy_setup() where we know for sure that we are running on a MoCA GENET instance, and do not override phydev->link since this is: - properly taken care of by the PHY library by getting the link UP/DOWN interrupts - this now runs everytime we call bcmgenet_open(), so we need to preserve whatever we detected before we went administratively DOWN and then UP - we need to make sure that MoCA PHYs start with a link DOWN during probe in order to force a link transition to occur To avoid a forward declaration, move bcmgenet_fixed_phy_link_update() above its caller.

Emil extends the reporting of the RSS key and hash table by adding support for x550 VFs. Jia-Ju Bai fixes a QoS issue in e1000e where the error handling lacked a call to pm_qos_remove_request() to cleanup the QoS request made in e1000_open(). Todd updates igb to report unsupported for ethtool coalesce settings that are not supported. Also updated the driver to use the ARRAY_SIZE() macro. Carolyn fixes and refactors the dynamic ITR code for i40e and i40evf which would never change dynamically. So update the switch() statement to have a default case and switch on "new_latency_range" versus the current ITR setting. Shannon cleans up i40e code, where there were un-needed goto's. Also clean up error status messages that were causing some confusion in PHY and FCoE setup error reports. Mitch updates the virtual channel interface to prepare for the x722 device and other future devices, so that the VF driver can report what its capable of supporting to the PF driver. Updates the i40evf driver to handle resets like Core or EMP resets, where the device is reinitialized and the VF will not get the same VSI.

2015-07-23i40e: provide correct API version to older VF driversMitch Williams1-0/+3
This driver fully supports VF drivers using both the 1.0 and 1.1 versions of the virtual channel API. However, VF drivers using version 1.0 get upset if we provide them with a version other than that, and refuse to play with us. Correct this by checking the VFs API version at the time that we store it off, and provide the correct version number back to the VF so we can all get along.

2015-07-23i40evf: handle big resetsMitch Williams3-46/+95
The most common type of reset that the VF will encounter is a PF reset that cascades down into a VF reset for each VF. In this case, the VF will always be assigned the same VSI and recovery is fairly simple. However, in the case of 'bigger' resets, such as a Core or EMP reset, when the device is reinitialized, it's probable that the VF will NOT get the same VSI. When this happens, the VF will not be able to recover, as it will continue to request resources for its original VSI. Add an extra state to the admin queue state machine so that the driver can re-request its configuration information at runtime. During reset recovery, set this bit in the aq_required field, and fetch the (possibly new) configuration information before attempting to bring the driver back up. Since the driver doesn't know what kind of reset it has encountered, this step is done even for a PF reset, but it doesn't hurt anything - it just gets the same VSI back.

The VF driver can now report what its capable of supporting, which then informs the PF driver when it sends the configuration information back to the VF.

This patch extends the reporting of the RSS key and hash table by adding support for X550 VFs. The difference is that X550 VFs have their own registers for RSS key and indirection table, so there is no need to query the PF. The RSS key and indirection table are stored in the adapter structure during the configuration of VFRSSRK and VFRETA which in turn can be used in ethtool for reporting. The logic for writing VFRETA is also changed to make sure that the indirection table is reported correctly. In addition this patch adds defines for the VFRETA entries and number of VFRSSRK registers as well as some whitespace cleanups.

2015-07-22bnx2x: Add MFW dump supportYuval Mintz4-0/+51
Devices with up-to-date management FW will be able to store register dumps on their persistent storage - in case management FW identifies a fatal error it would gather and store such dumps, which could later be retrieved using specific debug tools. This patch adds the necessary part in the driver in order to make the feature operational, as well as update users [under debug] during load in case their device contains a dump of a previous crash.

2015-07-22bnx2x: Utilize FW 7.12.30Yuval Mintz8-70/+136
This moves bnx2x into using 7.12.30 FW. Said firmware fixes the following: - Packets from a VF with pvid configured which were sent with a different vlan were transmitted instead of being discarded. - FCoE traffic might not recover after a failue while there's traffic to another function. In addition, this FW opens the door for the driver to implement several new features; Specifically, this enhances the device's support for encapsulated packets and will allow vxlan/geneve offloads to be added in the future, as well as vlan filtering offload.

2015-07-21ravb: fix ring memory allocationSergei Shtylyov1-25/+34
The driver is written as if it can adapt to a low memory situation allocating less RX skbs and TX aligned buffers than the respective RX/TX ring sizes. In reality though the driver would malfunction in this case. Stop being overly smart and just fail in such situation -- this is achieved by moving the memory allocation from ravb_ring_format() to ravb_ring_init(). We leave dma_map_single() calls in place but make their failure non-fatal by marking the corresponding RX descriptors with zero data size which should prevent DMA to an invalid addresses.
