2020-03-10ice: Correct setting VLAN pruningBrett Creeley
VLAN pruning is not always being set correctly due to a previous change that set Tx antispoof off. ice_vsi_is_vlan_pruning_ena() currently checks for both Tx antispoof and Rx pruning. The expectation for this function is to only check Rx pruning so fix the check.

2020-03-10ice: renegotiate link after FW DCB onDave Ertman
When switching from SW DCB to FW DCB it is necessary to renegotiate DCBx so that the FW agent can have up to date information about the DCB settings of the link partner. Perform an autoneg restart on the link when activating FW DCB.

2020-03-10ice: Fix corner case when switching from IEEE to CEEAvinash JD
While testing DCB for a corner case in which mode is switched from IEEE to CEE and pfc_ena bitmask unchanged then DCBX mode doesn't get updated. This is happening because the function ice_dcb_get_mode() is called in a "no change detected block" instead of "change detected block".

2020-03-10ice: Display Link detected via Ethtool in safe modeBrett Creeley
Currently the "Link detected" field is not shown when the device goes into safe mode. This is because the safe mode Ethtool ops does not set the get_link function. Fix this by setting the safe mode Ethtool op get_link function.

2020-03-10ice: Fix removing driver while bare-metal VFs pass trafficBrett Creeley
Currently, if there are bare-metal VFs passing traffic and the ice driver is removed, there is a possibility of VFs triggering a Tx timeout right before iavf_remove(). This is causing iavf_close() to not be called because there is a check in the beginning of iavf_remove() that bails out early if (adapter->state < IAVF_DOWN_PENDING). This makes it so some resources do not get cleaned up. Specifically, free_irq() is never called for data interrupts, which results in the following line of code to trigger: pci_disable_msix() free_msi_irqs() ... BUG_ON(irq_has_action(entry->irq + i)); ... To prevent the Tx timeout from occurring on the VF during driver unload for ice and the iavf there are a few changes that are needed. [1] Don't disable all active VF Tx/Rx queues prior to calling pci_disable_sriov. [2] Call ice_free_vfs() before disabling the service task. [3] Disable VF resets when the ice driver is being unloaded by setting the pf->state flag __ICE_VF_RESETS_DISABLED. Changing [1] and [2] allow each VF driver's remove flow to successfully send VIRTCHNL requests, which includes queue disable. This prevents unexpected Tx timeouts because the PF driver is no longer forcefully disabling queues. Due to [1] and [2] there is a possibility that the PF driver will get a VFLR or reset request over VIRTCHNL from a VF during PF driver unload. Prevent that by doing [3].

2020-03-10ice: Improve clarity of prints and variablesBrett Creeley
Currently when the device runs out of MSI-X interrupts a cryptic and unhelpful message is printed. This will cause confusion when hitting this case. Fix this by clearing up the error message for both SR-IOV and non SR-IOV use cases. Also, make a few minor changes to increase clarity of variables. 1. Change per VF MSI-X and queue pair variables in the PF structure. 2. Use ICE_NONQ_VECS_VF when determining pf->num_msix_per_vf instead of the magic number "1". This vector is reserved for the OICR. All of the resource tracking functions were moved to avoid adding any forward declaration function prototypes.

2020-03-10ice: allow bigger VFsMitch Williams
Unlike the XL710 series, 800-series hardware can allocate more than 4 MSI-X vectors per VF. This patch enables that functionality. We dynamically allocate vectors and queues depending on how many VFs are enabled. Allocating the maximum number of VFs replicates XL710 behavior with 4 queues and 4 vectors. But allocating a smaller number of VFs will give you 16 queues and 16 vectors.

2020-03-10iavf: Enable support for up to 16 queuesMitch Williams
Previous devices could only allocate 4 MSI-X vectors per VF so there was a limitation of 4 queues. 800-series hardware can allocate more than 4 MSI-X vectors, so expand the limitation on the number of queues that the driver can support to account for these capabilities. Fix ethtool channel operations to accommodate this change and adjust the reporting of max number of queues to what is given to us by the PF. Since we're not requesting queues above this value, just trigger reset to activate the queues, which we already own. Finally, fix a test condition that would display an incorrect error message.

2020-03-09Merge branch 'net-Add-support-for-Synopsys-DesignWare-XPCS'David S. Miller
Jose Abreu says: ==================== net: Add support for Synopsys DesignWare XPCS This adds support for Synopsys DesignWare XPCS in net subsystem and integrates it into stmmac. At 1/8, we start by removing the limitation of stmmac selftests that needed a PHY to pass all the tests. Then at 2/8 we use some helpers in stmmac so that some code can be simplified. At 3/8, we fallback to dev_fwnode() so that PCI based setups wich may not have CONFIG_OF can still use FW node. At 4/8, we adapt stmmac to the new PHYLINK changes as suggested by Russell King. We proceed by doing changes in PHYLINK in order to support XPCS: At 5/8 we add some missing speeds that USXGMII supports and at 6/8 we check if Autoneg is supported after initial parameters are validated. Support for XPCS is finally introduced at 7/8, along with the usage of it in stmmac driver at 8/8. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
