2015-04-02net/mlx4_en: Enable TX rate limit per VFIdo Shamay2-1/+187
Support granular QoS per VF, by implementing the ndo_set_vf_rate. Enforce a rate limit per VF when called, and enabled only for VFs in VST mode with user priority supported by the device. We don't enforce VFs to be in VST mode at the moment of configuration, but rather save the given rate limit and enforce it when the VF is moved to VST with user priority which is supported (currently 0). VST<->VGT or VST qos value state changes are disallowed when a rate limit is configured. Minimum BW share is not supported yet.

2015-04-02net/mlx4: Added qos_vport QP configuration in VST modeIdo Shamay5-1/+24
Granular QoS per VF feature introduce a new QP field, qos_vport. PF administrator can connect VF QPs to a certain QoS Vport, to inherit its proporties. Connecting QPs to the default QoS Vport (defined as 0) is always allowed, even when there are no allocated VPPs. At this point, only the default vport is connected to QPs.

Initialization of granular Qos per VF mechanism. Query the port availible VPPs and allocates those on all supported priorities in an equal share. Allocation is done only in SRIOV mode, when the feature is supported by the device and port type is Ethernet. Allocation currently is done only on the default priority 0.

2015-04-02net/mlx4: Add mlx4_SET_VPORT_QOS implementationIdo Shamay3-0/+134
Add the SET_VPORT_QOS device command, which is ntended for virtual granular QoS configuration per VF in SRIOV mode. The SET_VPORT_QOS command sets and queries QoS parameters of a VPort. Each priority allowed for a VPort is assigned with a share of the BW, and a BW limitation. QoS parameters can be modified at any time, but must be initialized before any QP is associated with the VPort.

2015-04-02net/mlx4: Add mlx4_ALLOCATE_VPP implementationIdo Shamay3-0/+112
Implements device ALLOCATE_VPP command, to be used for granular QoS configuration of VFs by the PF device. Defines and queries the amount of VPPs assigned to each port, and the amount of VPPs assigned to each priority of each port. Once the total VPPs are split between the priorities of a port, they may be assigned with a share of the BW or a rate limit. Split into two functions (get/set) whoch are supplied with mlx4_alloc_vpp_context and physical port number.

2015-04-02net/mlx4_en: Change loopback only upon feature changeIdo Shamay2-7/+10

2015-04-02net/mlx4: Add RSS support for fragmented IP datagramsIdo Shamay3-0/+15
Enable RSS support for fragmented IP packets, when device supports it. Until now, fragmented IP packets were directed only to the default_qpn. Since IP fragments (datagram) have no upper protocols (L3 IP packets), hash is performed on 3-tuple - dst MAC, source IP and dest IP. The HW makes sure that this holds for the 1st fragment too, so all fragments go to the same QP.

2015-04-01net: bcmgenet: enable MoCA link state change detectionPetri Gynther3-2/+24
Currently, MoCA fixed PHYs are always in link-up state, regardless of whether the link is actually up or not. Add code to properly detect MoCA link state changes and to reflect the new state in MoCA fixed PHY. Only GENET V3 and V4 MACs are capable of detecting MoCA link state changes. The code works as follows: 1. GENET MAC detects MoCA link state change and issues UMAC_IRQ_LINK_UP or UMAC_IRQ_LINK_DOWN interrupt. 2. Link up/down interrupt is processed in bcmgenet_irq_task(), which calls phy_mac_interrupt(). 3. phy_mac_interrupt() updates the fixed PHY phydev->link and kicks the PHY state machine. 4. PHY state machine proceeds to read the fixed PHY link status register. 5. When the fixed PHY link status register is being read, the new function bcmgenet_fixed_phy_link_update() gets called. It copies the fixed PHY phydev->link value to the fixed PHY status->link. 6. PHY state machine receives the new link state of the fixed PHY. 7. MoCA fixed PHY link state now correctly reflects the real MoCA hardware link state. Signed-off-by: Petri Gynther <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2015-04-01bnx2x: Fix kdump when iommu=onYuval Mintz1-23/+16
When IOMM-vtd is active, once main kernel crashes unfinished DMAE transactions will be blocked, putting the HW in an error state which will cause further transactions to timeout. Current employed logic uses wrong macros, causing the first function to be the only function that cleanups that error state during its probe/load. This patch allows all the functions to successfully re-load in kdump kernel. Signed-off-by: Yuval Mintz <[email protected]> Signed-off-by: Ariel Elior <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2015-04-01bnx2x: Fix kdump on 4-port deviceYuval Mintz1-18/+35
When running in a kdump kernel, it's very likely that due to sync. loss with management firmware the first PCI function to probe and reach the previous unload flow would decide it can reset the chip and continue onward. While doing so, it will only close its own Rx port. On a 4-port device where 2nd port on engine is a 1g-port, the 2nd port would allow ingress traffic after the chip is reset [assuming it was active on the first kernel]. This would later cause a HW attention. This changes driver flow to close both ports' 1g capabilities during the previous driver unload flow prior to the chip reset.

2015-04-01MIPS: BCM47xx: Move NVRAM header to the include/linux/.Rafał Miłecki2-2/+2
There are two reasons for having this header in the common place: 1) Simplifying drivers that read NVRAM entries. We will be able to safely call bcm47xx_nvram_* functions without #ifdef-s. 2) Getting NVRAM driver out of MIPS arch code. This is needed to support BCM5301X arch which also requires this NVRAM driver. Patch for that will follow once we get is reviewed.
