intel-ethernet: rename i40evf to iavf

2018-09-18T15:43:03Z

Rename the Intel Ethernet Adaptive Virtual Function driver (i40evf) to a new name (iavf) that is more consistent with the ongoing maintenance of the driver as the universal VF driver for multiple product lines. This first patch fixes up the directory names and the .ko name, intentionally ignoring the function names inside the driver for now. Basically this is the simplest patch that gets the rename done and will be followed by other patches that rename the internal functions. This patch also addresses a couple of string/name issues and updates the Copyright year. Also, made sure to add a MODULE_ALIAS to the old name.

i40e(vf): remove i40e_ethtool_stats.h header file

2018-09-08T17:06:17Z

Essentially reverts commit 8fd75c58a09a ("i40e: move ethtool stats boiler plate code to i40e_ethtool_stats.h", 2018-08-30), and additionally moves the similar code in i40evf into i40evf_ethtool.c. The code was intially moved from i40e_ethtool.c into i40e_ethtool_stats.h as a way of better logically organizing the code. This has two problems. First, we can't have an inline function with variadic arguments on all platforms. Second, it gave the appearance that we had plans to share code between the i40e and i40evf drivers, due to having a near copy of the contents in the i40evf/i40e_ethtool_stats.h file. Patches which actually attempt to combine or share code between the i40e and i40evf drivers have not materialized, and are likely a ways off. Rather than fixing the one function which causes build issues, just move this code back into the i40e_ethtool.c and i40evf_ethtool.c files. Note that we also change these functions back from static inlines to just statics, since they're no longer in a header file. We can revisit this if/when work is done to actually attempt to share code between drivers. Alternatively, this stats code could be made more generic so that it can be shared across drivers as part of ethtool kernel work. Signed-off-by: Jacob Keller Signed-off-by: David S. Miller

i40evf: cancel workqueue sync for adminq when a VF is removed

2018-08-30T20:53:04Z

If a VF is being removed, there is no need to continue with the workqueue sync for the adminq task, thus cancel it. Without this call, when VFs are created and removed right away, there might be a chance for the driver to crash with events stuck in the adminq.

i40evf: Don't enable vlan stripping when rx offload is turned on

2018-08-30T20:53:04Z

With current implementation of i40evf_set_features when user sets any offload via ethtool we set I40EVF_FLAG_AQ_ENABLE_VLAN_STRIPPING as a required aq which triggers driver to call i40evf_enable_vlan_stripping. This shouldn't take place. This patches fixes it by setting the flag only when VLAN offload is turned on. Signed-off-by: Patryk Małek Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher

i40evf: set IFF_UNICAST_FLT flag for the VF

2018-08-30T20:53:04Z

Set IFF_UNICAST_FLT flag for the VF to prevent it from entering promiscuous mode when macvlan is added to the VF. Signed-off-by: Lihong Yang Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher

i40evf: Validate the number of queues a PF sends

2018-08-30T20:53:04Z

A PF can send any number of queues to the VF and the VF may not be able to support that many. Check to see that the number of queues is less than or equal to the max number of queues the VF can have. Signed-off-by: Paul M Stillwell Jr Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher

i40evf: Change a VF mac without reloading the VF driver

2018-08-30T20:53:03Z

Add possibility to change a VF mac address from host side without reloading the VF driver on the guest side. Without this patch it is not possible to change the VF mac because executing i40evf_virtchnl_completion function with VIRTCHNL_OP_GET_VF_RESOURCES opcode resets the VF mac address to previous value.

i40evf: update ethtool stats code and use helper functions

2018-08-30T20:53:03Z

Fix a bug in the way we handled VF queues, by always showing stats for the maximum number of queues, even if they aren't allocated. It is not safe to change the number of strings reported to ethtool, as grabbing statistics occurs over multiple ethtool ops for which the rtnl_lock() cannot be held the entire time. Avoid this by always reporting queue stats for the maximum number of queues in the netdevice. Share some of the helper functionality for adding stats with the PF code in i40e_ethtool_stats.h This should reduce the chance of potential future bugs, and make adding new statistics easier. Note for the queue stats, unlike the PF driver we do not keep an array of queue pointers, but an array of queues, so care must be taken to avoid accessing queue memory that hasn't yet been allocated.

i40e: Add AQ command for rearrange NVM structure

2018-08-07T19:20:45Z

During switching between old NVM structure approach (called structured NVM) to new one (called flat NVM) or backward flash needs to be rearranged to required NVM structure. This is a part of transition from one NVM structure to another. The function is introduced to command firmware to start rearrangement process.
