Rejecting non-native endian BTF overlapped with the addition of support for it. The rest were more simple overlapping changes, except the renesas ravb binding update, which had to follow a file move as well as a YAML conversion. Signed-off-by: David S. Miller <davem@davemloft.net>
2020-09-25intel-ethernet: clean up W=1 warnings in kdocJesse Brandeburg4-14/+14
This takes care of all of the trivial W=1 fixes in the Intel Ethernet drivers, which allows developers and maintainers to build more of the networking tree with more complete warning checks. There are three classes of kdoc warnings fixed: - cannot understand function prototype: 'x' - Excess function parameter 'x' description in 'y' - Function parameter or member 'x' not described in 'y' All of the changes were trivial comment updates on function headers. Inspired by Lee Jones' series of wireless work to do the same.

2020-07-30iavf: use generic power managementVaibhav Gupta1-33/+12
With the support of generic PM callbacks, drivers no longer need to use legacy .suspend() and .resume() in which they had to maintain PCI states changes and device's power state themselves. The required operations are done by PCI core. PCI drivers are not expected to invoke PCI helper functions like pci_save/restore_state(), pci_enable/disable_device(), pci_set_power_state(), etc. Their tasks are completed by PCI core itself.

2020-07-01iavf: Fix updating statisticsTony Nguyen1-1/+4
Commit bac8486116b0 ("iavf: Refactor the watchdog state machine") inverted the logic for when to update statistics. Statistics should be updated when no other commands are pending, instead they were only requested when a command was processed. iavf_request_stats() would see a pending request and not request statistics to be updated. This caused statistics to never be updated; fix the logic.

2020-06-25net/intel: remove driver versions from Intel driversJeff Kirsher4-23/+1
As with other networking drivers, remove the unnecessary driver version from the Intel drivers. The ethtool driver information and module version will then report the kernel version instead. For ixgbe, i40e and ice drivers, the driver passes the driver version to the firmware to confirm that we are up and running. So we now pass the value of UTS_RELEASE to the firmware. This adminq call is required per the HAS document. The Device then sends an indication to the BMC that the PF driver is present. This is done using Host NC Driver Status Indication in NC-SI Get Link command or via the Host Network Controller Driver Status Change AEN. What the BMC may do with this information is implementation-dependent, but this is a standard NC-SI 1.1 command we honor per the HAS.

2020-06-11iavf: fix speed reporting over virtchnlBrett Creeley4-21/+120
Link speeds are communicated over virtchnl using an enum virtchnl_link_speed. Currently, the highest link speed is 40Gbps which leaves us unable to reflect some speeds that an ice VF is capable of. This causes link speed to be misreported on the iavf driver. Allow for communicating link speeds using Mbps so that the proper speed can be reported for an ice VF. Moving away from the enum allows us to communicate future speed changes without requiring a new enum to be added. In order to support communicating link speeds over virtchnl in Mbps the following functionality was added: - Added u32 link_speed_mbps in the iavf_adapter structure. - Added the macro ADV_LINK_SUPPORT(_a) to determine if the VF driver supports communicating link speeds in Mbps. - Added the function iavf_get_vpe_link_status() to fill the correct link_status in the event_data union based on the ADV_LINK_SUPPORT(_a) macro. - Added the function iavf_set_adapter_link_speed_from_vpe() to determine whether or not to fill the u32 link_speed_mbps or enum virtchnl_link_speed link_speed field in the iavf_adapter structure based on the ADV_LINK_SUPPORT(_a) macro. - Do not free vf_res in iavf_init_get_resources() as vf_res will be accessed in iavf_get_link_ksettings(); memset to 0 instead. This memory is subsequently freed in iavf_remove().

2020-03-10iavf: Enable support for up to 16 queuesMitch Williams4-40/+11
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.

2020-02-26iavf: use tc_cls_can_offload_and_chain0() instead of chain checkJiri Pirko1-3/+5
Looks like the iavf code actually experienced a race condition, when a developer took code before the check for chain 0 was put to helper. So use tc_cls_can_offload_and_chain0() helper instead of direct check and move the check to _cb() so this is similar to i40e code.

2020-01-09iavf: remove current MAC address filter on VF resetStefan Assmann3-4/+18
Currently MAC filters are not altered during a VF reset event. This may lead to a stale filter when an administratively set MAC is forced by the PF. For an administratively set MAC the PF driver deletes the VFs filters, overwrites the VFs MAC address and triggers a VF reset. However the VF driver itself is not aware of the filter removal, which is what the VF reset is for. The VF reset queues all filters present in the VF driver to be re-added to the PF filter list (including the filter for the now stale VF MAC address) and triggers a VIRTCHNL_OP_GET_VF_RESOURCES event, which provides the new MAC address to the VF. When this happens i40e will complain and reject the stale MAC filter, at least in the untrusted VF case. i40e 0000:08:00.0: Setting MAC 3c:fa:fa:fa:fa:01 on VF 0 iavf 0000:08:02.0: Reset warning received from the PF iavf 0000:08:02.0: Scheduling reset task i40e 0000:08:00.0: Bring down and up the VF interface to make this change effective. i40e 0000:08:00.0: VF attempting to override administratively set MAC address, bring down and up the VF interface to resume normal operation i40e 0000:08:00.0: VF 0 failed opcode 10, retval: -1 iavf 0000:08:02.0: Failed to add MAC filter, error IAVF_ERR_NVM To avoid re-adding the stale MAC filter it needs to be removed from the VF driver's filter list before queuing the existing filters. Then during the VIRTCHNL_OP_GET_VF_RESOURCES event the correct filter needs to be added again, at which point the MAC address has been updated. As a bonus this change makes bringing the VF down and up again superfluous for the administratively set MAC case.

2019-11-08iavf: initialize ITRN registers with correct valuesNicholas Nunley1-2/+2
Since commit 92418fb14750 ("i40e/i40evf: Use usec value instead of reg value for ITR defines") the driver tracks the interrupt throttling intervals in single usec units, although the actual ITRN registers are programmed in 2 usec units. Most register programming flows in the driver correctly handle the conversion, although it is currently not applied when the registers are initialized to their default values. Most of the time this doesn't present a problem since the default values are usually immediately overwritten through the standard adaptive throttling mechanism, or updated manually by the user, but if adaptive throttling is disabled and the interval values are left alone then the incorrect value will persist. Since the intended default interval of 50 usecs (vs. 100 usecs as programmed) performs better for most traffic workloads, this can lead to performance regressions. This patch adds the correct conversion when writing the initial values to the ITRN registers.

2019-09-11iavf: fix MAC address setting for VFs when filter is rejectedStefan Assmann2-1/+7
Currently iavf unconditionally applies MAC address change requests. This brings the VF in a state where it is no longer able to pass traffic if the PF rejects a MAC filter change for the VF. A typical scenario for a rejected MAC filter is for an untrusted VF to request to change the MAC address when an administratively set MAC is present. To keep iavf working in this scenario the MAC filter handling in iavf needs to act on the PF reply regarding the MAC filter change. In the case of an ack the new MAC address gets set, whereas in the case of a nack the previous MAC address needs to stay in place.

This preparation patch reduces the number of changes to adapt the existing drivers to use the flow block callback API. This new helper function takes a flow block list per-driver, which is set to NULL until this driver list is used. This patch also introduces the flow_block_command and flow_block_binder_type enumerations, which are renamed to use FLOW_BLOCK_* in follow up patches.

2019-06-17iavf: Fix the math for valid length for ADq enableAvinash Dayanand1-1/+1
There was a calculation error in virtchnl regarding the valid length which was fixed recently and a corresponding change needs to go into the code while we enable ADq.

2019-06-17iavf: Change GFP_KERNEL to GFP_ATOMIC in kzalloc()Aleksandr Loktionov1-1/+1
iavf_add_vlan() is being called in atomic context so kzalloc() needs GFP_ATOMIC. This patch fixes it. Signed-off-by: Aleksandr Loktionov <aleksandr.loktionov@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2019-06-17iavf: wait longer for close to completeMitch Williams1-1/+1
On some hardware/driver/architecture combinations, it may take longer than 200msec for all close operations to be completed, causing a spurious error message to be logged. Increase the timeout value to 500msec to avoid this erroneous error.

2019-06-17iavf: use signed variableMitch Williams1-1/+1
The counter variable in iavf_clean_tx_irq starts out negative and climbs to 0. So allocating it as u16 is actually a really bad idea that just happens to work because the value underflows and overflows consistently on most architectures. Replace the u16 with an int so signed math works as expected.

2019-06-17iavf: Create VLAN tag elements starting from the first elementAkeem G Abodunrin1-2/+1
This patch changes how VLAN tag are being populated and programmed into the HW - Instead of start adding VF VLAN tag from the last member of the element list, start from the first member of the list, until number of allowed VLAN tags is exhausted in the HW.
