From d73dd1275e70023a5a28af558791a64392c60edf Mon Sep 17 00:00:00 2001 From: Mateusz Palczewski Date: Mon, 10 Jan 2022 16:06:38 +0100 Subject: [PATCH 1/7] iavf: Add support for 50G/100G in AIM algorithm Advanced link speed support was added long back, but adding AIM support was missed. This patch adds AIM support for advanced link speed support, which allows the algorithm to take into account 50G/100G link speeds. Also, other previous speeds are taken into consideration when advanced link speeds are supported.

This must occur prior to __IAVF_CONFIG_ADAPTER, and the driver must wait for the response from the PF. To handle this, the __IAVF_INIT_GET_OFFLOAD_VLAN_V2_CAPS state was introduced. This state is intended to process the response from the VLAN V2 caps message. This works ok, but is difficult to extend to adding more extended capability exchange. Existing (and future) AVF features are relying more and more on these sort of extended ops for processing additional capabilities. Just like VLAN V2, this exchange must happen prior to __IAVF_CONFIG_ADPATER. Since we only send one outstanding AQ message at a time during init, it is not clear where to place this state. Adding more capability specific states becomes a mess. Instead of having the "previous" state send a message and then transition into a capability-specific state, introduce __IAVF_EXTENDED_CAPS state. This state will use a list of extended_caps that determines what messages to send and receive. As long as there are extended_caps bits still set, the driver will remain in this state performing one send or one receive per state machine loop. Refactor the VLAN V2 negotiation to use this new state, and remove the capability-specific state. This makes it significantly easier to add a new similar capability exchange going forward. Extended capabilities are processed by having an associated SEND and RECV extended capability bit. During __IAVF_EXTENDED_CAPS, the driver checks these bits in order by feature, first the send bit for a feature, then the recv bit for a feature. Each send flag will call a function that sends the necessary response, while each receive flag will wait for the response from the PF. If a given feature can't be negotiated with the PF, the associated flags will be cleared in order to skip processing of that feature.

This leads to confusion as functions return both Linux errno values and status codes intermixed. Reporting status codes as if they were "errno" values can lead to confusion when reviewing error logs. Additionally, it can lead to unexpected behavior if a return value is not interpreted properly. Fix this by introducing iavf_status_to_errno, a switch that explicitly converts from the status codes into an appropriate error value. Also introduce a virtchnl_status_to_errno function for the one case where we were returning both virtchnl status codes and iavf_status codes in the same function.

These are all assigning iavf_status values to int values. Fix this and explicitly assign int values if iavf_status is not IAVF_SUCCESS. Also, refactor a small amount of duplicated code that can be reused by all of the previously mentioned functions. Finally, fix some spacing errors for variable assignment and get rid of all the goto statements in the refactored functions for clarity.
