2015-06-03e1000e: fix systim issuesYanir Lubetkin
Two issues involving systim were reported. 1. Clock is not running in the correct frequency 2. In some situations, systim values were not incremented linearly This patch fixes the hardware clock configuration and the spurious non-linear increment.

2015-06-03e1000e: fix logical error in flush_desc_ringsYanir Lubetkin
The condition under which the flush should occur was reversed. The fix should be applied before any HW reset (unless followed by bus reset) and before any power state transition from D0. If E1000_FEXTNVM7_NEED_DESCRING_FLUSH bit is set in FEXTNVM7 and TDLEN > 0 the Tx ring should be flushed. (fixes ~95% of the hang states). If the E1000_FEXTNVM7_NEED_DESCRING_FLUSH did not clear, we should also flush the RX ring. Bug was caught by Alexander Duyck during a code review when examining this fix.

2015-06-03e1000e: i219 fix unit hang on reset and runtime D3Yanir Lubetkin
Unit hang may occur if multiple descriptors are available in the rings during reset or runtime suspend. This state can be detected by testing bit 8 in the FEXTNVM7 register. If this bit is set and there are pending descriptors in one of the rings, we must flush them prior to reset. Same applies entering runtime suspend.

Shradha Shah says: ==================== sfc: ndo_get_phys_port_id, vadaptor stats and PF unload when Vf's assigned to guest This is the third and last instalment of SRIOV for EF10 patches. This patch set includes implementation of ndo_get_phys_port_id and changes to the MAC statistics code in order to support vadaptor statistics. It also includes code to deal with PF unload when Vf's are still assigned to the guest. The first couple of patches create sysfs files for physical port and link control flags which are particularly useful when we have enabled a large number of VF's. These patches have been tested with and without CONFIG_SFC_SRIOV. The creation and content of the sysfs files has been tested. The statistics are tested using ethtool for monitoring. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2015-06-02sfc: leak vports if a VF is assigned during PF unloadDaniel Pieczko
If any VF is assigned as the PF is unloaded, do not attempt to remove its vport or the vswitch. These will be removed if the driver binds to the PF again, as an entity reset occurs during probe. A 'force' flag is added to efx_ef10_pci_sriov_disable() to distinguish between disabling SR-IOV and driver unload. SR-IOV cannot be disabled if VFs are assigned to guests. If the PF driver is unloaded while VFs are assigned, the driver may try to bind to the VF again at a later point if the driver has been reloaded and the VF returns to the same domain as the PF. In this case, the PF will not have a VF data structure, so the VF can check this and drop out of probe early. In this case, efx->vf_count will be zero but VFs will be present. The user is advised to remove the VF and re-create it. The check at the beginning of efx_ef10_pci_sriov_disable() that efx->vf_count is non-zero is removed to allow SR-IOV to be disabled in this case. Also, if the PF driver is unloaded, it will disable SR-IOV to remove these unknown VFs. By not disabling bus-mastering if VFs are still assigned, the VF will continue to pass traffic after the PF has been removed. When using the max_vfs module parameter, if VFs are already present do not try to initialise any more. Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S.

2015-06-02sfc: force removal of VF and vport on driver removalDaniel Pieczko
When the driver unloads, force the unbind and removal of any VFs in the host with the PF. The PF cannot remove vports and vswitches if they are still being used by a VF driver, and when unloading the sfc driver the removal order is not guaranteed, so the instruction from the PF to the VF to unbind enforces a suitable ordering so that vswitches and vports can be removed. As a result of this, manually unbinding the driver from a single PF will result in all of its VFs in the host also being removed.

2015-06-02sfc: don't update stats on VF when called in atomic contextDaniel Pieczko
The ifenslave command to set up a bond runs in an atomic context, and it queries the stats on the devices that are being enslaved. A VF needs to make an MCDI call to update its stats, which is not allowed in atomic context. The releasing of the stats_lock is moved to the beginning of the VF stats update function so that in_interrupt() can be used; it must be taken again before returning from this function.

2015-06-02sfc: suppress vadaptor stats when EVB is not presentDaniel Pieczko
The raw_mask array is not initialised, so it needs to be explicitly set to zero in the 'else' branch. If the EVB capability is not present, a port cannot have multiple functions so the per-port MAC stats are correct and should match the corresponding vadaptor stats, so this redundancy can be removed from the ethtool stats output.

2015-06-02sfc: suppress ENOENT error messages from MC_CMD_MAC_STATSDaniel Pieczko
MC_CMD_MAC_STATS can be called on a function before a vadaptor has been created, as the kernel can call into this through ndo_get_stats/ndo_get_stats64. If MC_CMD_MAC_STATS is called before the DMA queues have been setup, so that a vadaptor has not been created yet, firmware will return ENOENT. This is expected, so suppress the MCDI error message in this case. Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-06-02sfc: update netdevice statistics to use vadaptor statsDaniel Pieczko

Scott Feldman says: ==================== rocker: enable by default untagged VLAN support This patch set is a followup to Simon Horman's RFC patch: [PATCH/RFC net-next] rocker: by default accept untagged packets Now, on port probe, we install untagged VLAN (vid=0) support for each port as the default. This is equivalent to the command: bridge vlan add vid 0 dev DEV self Accepting untagged VLAN pkts is a reasonable default, but the user could override this with: bridge vlan del vid 0 dev DEV self With this, we no longer need 8021q module to install vid=0 when port interface opens. In fact, we don't need support for legacy VLAN ndo ops at all since they're superseded by bridge_setlink/dellink. So remove legacy VLAN ndo ops support in driver. (The legacy VLAN ndo ops are supported by bonding/team drivers, but don't fit into the transaction model offered by switchdev, so switching all VLAN functions to bridge_setlink/dellink switchdev support gets us stacked driver + transaction model support). ==================== Signed-off-by: David S.

2015-06-01rocker: remove support for legacy VLAN ndo opsScott Feldman
Remove support for legacy ndo ops .ndo_vlan_rx_add_vid/.ndo_vlan_rx_kill_vid. Rocker will use bridge_setlink/dellink exclusively for VLAN add/del operations. The legacy ops are needed if using 8021q driver module to setup VLANs on the port. But an alternative exists in using bridge_setlink/delink to setup VLANs, which doesn't depend on 8021q module. So rocker will switch to the newer setlink/dellink ops. VLANs can added/delete from the port, regardless if port is bridged or not, using the bridge commands: bridge vlan [add|del] vid VID dev DEV self (Yes, I agree it's confusing to use the "bridge" command to set a VLAN on a non-bridged port). Using setlink/dellink over legacy ops let's us handle the stacked driver case automatically. It's built-in. setlink also pass additional flags (PVID, egress untagged) that aren't available with the legacy ops. Signed-off-by: Scott Feldman <sfeldma@gmail.com> Signed-off-by: David S.

2015-06-01rocker: install/remove router MAC for untagged VLAN when joining/leaving bridgeScott Feldman
When the port joins a bridge, the port's internal VLAN ID needs to change to the bridge's internal VLAN ID. Likewise, when leaving the bridge, the internal VLAN ID reverts back the port's original internal VLAN ID. (The internal VLAN ID is used by device to internally mark untagged pkts with some VLAN, which will eventually be removed on egress...think PVID). When the internal VLAN ID changes, we need to update the VLAN table entries and the router MAC entries for IP/IPv6 to reflect the new internal VLAN ID. This patch makes use of the common rocker_port_vlan_add/del functions to make sure the tables are updated for the current internal VLAN ID.

This is equivalent to running the command: bridge vlan add vid 0 dev DEV self A user could, if they wanted, manaully removing untagged support from the port by running the command: bridge vlan del vid 0 dev DEV self But installing it by default on port initialization gives the normal expected behavior.

2015-06-01rocker: zero allocate ports arrayScott Feldman
When allocating the array of rocker port pointers, zero the array values so we can test for !NULL to see if port is allocated/registered. We'll need this later when installing untagged VLAN support for each port, during port probe. It's a long story, but to install a VLAN (vid=0 for untagged, in this case) on a port, we'll need to scan other ports to see if the VLAN group for that VLAN has been setup. To scan the other ports, we need to walk the port array. Signed-off-by: Scott Feldman <sfeldma@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
