Declare the returntype of batadv_compare_eth as bool. The function called inside this helper function (ether_addr_equal_unaligned) also uses bool as return value, so there is no need to return int.

orig_ifinfo is dereferenced multiple times in batadv_iv_ogm_update_seqnos before the check for NULL is done. The function also exists at the beginning when orig_ifinfo would have been NULL. This makes the check at the end unnecessary and only confuses the reader/code analyzers. Signed-off-by: NSven Eckelmann <sven@narfation.org> Signed-off-by: NMarek Lindner <mareklindner@neomailbox.ch>

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: NDavid S. Miller <davem@davemloft.net>

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: NShradha Shah <sshah@solarflare.com> Signed-off-by: NDavid S.

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.

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.

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.

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: NShradha Shah <sshah@solarflare.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

The netdevice statistics (in /proc/net/dev) are per-function stats so they must use the vadaptor stats. Change the use of MAC stats to vadaptor stats, and remove any statistics that can only be measured per-port. All stats that are removed will be shown as zeroes when these statistics are displayed.
