i40e: Update status codes

2018-10-31T17:57:43Z

Add a few new status code which will be used by the ice driver, and rename a few to make them more consistent. Error code are mapped to similar values as in i40e_status.h, so as to be compatible with older VF drivers not using this status enum.

virtchnl: use u8 type for a field in the virtchnl_filter struct

2018-08-30T20:53:04Z

The virtchnl_filter struct has a field called field_flags. A previous commit mistakenly had the type to be a __u8. What we want is for the field to be an unsigned 8 bit value, so let's just use the existing kernel type u8 for that.

virtchnl: Add filter data structures

2018-02-14T17:43:22Z

This patch adds infrastructure to send virtchnl messages to the PF to configure filters on the VF. The patch adds a struct called virtchnl_filter which contains information about the fields in the user-specified tc filter.

virtchnl: Add a macro to check the size of a union

2018-02-14T17:43:22Z

This patch adds a macro to check if the size of a union is correct. It throws a divide by zero error if the union is not of the correct size. Signed-off-by: Harshitha Ramamurthy Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher

virtchnl: Add virtchl structures to support queue channels

2018-02-14T17:43:22Z

This patch defines new structs in support of the virtchannel message that the VF sends to the PF to create a queue channel specified by the user via tc tool. Signed-off-by: Harshitha Ramamurthy Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher

i40e/i40evf: don't trust VF to reset itself

2017-10-13T21:27:13Z

When using 'ethtool -L' on a VF to change number of requested queues from PF, we shouldn't trust the VF to reset itself after making the request. Doing it that way opens the door for a potentially malicious VF to do nasty things to the PF which should never be the case. This makes it such that after VF makes a successful request, PF will then reset the VF to institute required changes. Only if the request fails will PF send a message back to VF letting it know the request was unsuccessful. Testing-hints: There should be no real functional changes. This is simply hardening against a potentially malicious VF. Signed-off-by: Alan Brady Tested-by: Andrew Bowers Signed-off-by: Jeff Kirsher

i40e: Enable VF to negotiate number of allocated queues

2017-09-29T19:51:01Z

Currently the PF allocates a default number of queues for each VF and cannot be changed. This patch enables the VF to request a different number of queues allocated to it. This patch also adds a new virtchnl op and capability flag to facilitate this negotiation. After the PF receives a request message, it will set a requested number of queues for that VF. Then when the VF resets, its VSI will get a new number of queues allocated to it. This is a best effort request and since we only allocate a guaranteed default number, if the VF tries to ask for more than the guaranteed number, there may not be enough in HW to accommodate it unless other queues for other VFs are freed. It should also be noted decreasing the number queues allocated to a VF to below the default will NOT enable the allocation of more than 32 VFs per PF and will not free queues guaranteed to each VF by default.

i40e/i40evf: support for VF VLAN tag stripping control

2017-08-27T22:47:43Z

This patch gives VF capability to control VLAN tag stripping via ethtool. As rx-vlan-offload was fixed before, now the VF is able to change it using "ethtool --offload rxvlan on/off" settings. Signed-off-by: Mariusz Stachura Signed-off-by: Jeff Kirsher
