2020-05-22net/mlx5: Avoid processing commands before cmdif is readyEran Ben Elisha
When driver is reloading during recovery flow, it can't get new commands till command interface is up again. Otherwise we may get to null pointer trying to access non initialized command structures. Add cmdif state to avoid processing commands while cmdif is not ready.

2020-05-22net/mlx5: Fix a race when moving command interface to events modeEran Ben Elisha
After driver creates (via FW command) an EQ for commands, the driver will be informed on new commands completion by EQE. However, due to a race in driver's internal command mode metadata update, some new commands will still be miss-handled by driver as if we are in polling mode. Such commands can get two non forced completion, leading to already freed command entry access. CREATE_EQ command, that maps EQ to the command queue must be posted to the command queue while it is empty and no other command should be posted. Add SW mechanism that once the CREATE_EQ command is about to be executed, all other commands will return error without being sent to the FW. Allow sending other commands only after successfully changing the driver's internal command mode metadata. We can safely return error to all other commands while creating the command EQ, as all other commands might be sent from the user/application during driver load. Application can rerun them later after driver's load was finished.

2020-05-22net/mlx5: Add command entry handling completionMoshe Shemesh
When FW response to commands is very slow and all command entries in use are waiting for completion we can have a race where commands can get timeout before they get out of the queue and handled. Timeout completion on uninitialized command will cause releasing command's buffers before accessing it for initialization and then we will get NULL pointer exception while trying access it. It may also cause releasing buffers of another command since we may have timeout completion before even allocating entry index for this command. Add entry handling completion to avoid this race.

By default E-Switch egress ACL forwards eswitch vports egress packets to their corresponding NIC/VF vports. With this cap enabled, the driver is allowed to alter this behavior and forward packets to arbitrary NIC/VF vports with the following limitations: a. Multiple processing paths are supported if all of the following conditions are met: - HCA_CAP.egress_acl_forward_to_vport is set ==1. - A destination of type Flow Table only appears once, as the last destination in the list. - Vport destination is supported if HCA_CAP.egress_acl_forward_to_vport==1. Vport must not be the Uplink. b. Flow_tag not supported. c. This table is only applicable after an FDB table is created. d. Push VLAN action is not supported. e. Pop VLAN action cannot be added concurrently to this table and FDB table. This feature will be used during port failover in bonding scenario where two VFs representors are bonded to handle failover egress traffic (VM's ingress/receive traffic).

The new raw APIs considered the input of 'pp_rate_limit_context', uid, 'dedicated', upon looking for an existing entry. This raw mode enables future device specification data in the raw context without changing the existing logic and code. The ability to ask for a dedicated entry gives control for application to allocate entries according to its needs. A dedicated entry may not be used by some other process and it also enables the process spreading its resources to some different entries for use different hardware resources as part of enforcing the rate.

2020-02-27net/mlx5e: Eswitch, Use per vport tables for mirroringEli Cohen
When using port mirroring, we forward the traffic to another table and use that table to forward to the mirrored vport. Since the hardware loses the values of reg c, and in particular reg c0, we fail the match on the input vport which previously existed in reg c0. To overcome this situation, we use a set of per vport tables, positioned at the lowest priority, and forward traffic to those tables. Since these tables are per vport, we can avoid matching on reg c0.

We add an API so callers can add all the used reg_c0 values (tags) and for each of those we add a restore rule.

2020-02-19net/mlx5: E-Switch, Move source port on reg_c0 to the upper 16 bitsPaul Blakey
Multi chain support requires the miss path to continue the processing from the last chain id, and for that we need to save the chain miss tag (a mapping for 32bit chain id) on reg_c0 which will come in a next patch. Currently reg_c0 is exclusively used to store the source port metadata, giving it 32bit, it is created from 16bits of vcha_id, and 16bits of vport number. We will move this source port metadata to upper 16bits, and leave the lower bits for the chain miss tag. We compress the reg_c0 source port metadata to 16bits by taking 8 bits from vhca_id, and 8bits from the vport number. Since we compress the vport number to 8bits statically, and leave two top ids for special PF/ECPF numbers, we will only support a max of 254 vports with this strategy.

Each record is identified by the segment name (ASCII). During the driver's course of life, users (like reporters) may request dumps per segment. The user should create a command providing the segment identifier (SW enumeration) and command keys. In return, the user receives a command context. In order to receive the dump, the user should supply the command context and a memory (aligned to a PAGE) on which the dump content will be written. Since the dump may be larger than the given memory, the user may resubmit the command until received an indication of end-of-dump. It is the user's responsibility to destroy the command.

2020-01-25IB/mlx5: Return the administrative GUID if existsDanit Goldberg
A user can change the operational GUID (a.k.a affective GUID) through link/infiniband. Therefore it is preferred to return the currently set GUID if it exists instead of the operational. This way the PF can query which VF GUID will be set in the next bind. In order to align with MAC address, zero is returned if administrative GUID is not set.

This allows fs_core to manage the connections and levels of the flow tables hierarcy to prevent loops, but restricts us with the number of supported chains and priorities. Introduce unmananged flow tables, allowing the user to manage the flow table connections. A unamanged table is detached from the fs_core flow table hierarcy, and is only connected back to the hierarchy by explicit FTEs forward actions. This will be used together with firmware that supports ignoring the flow table levels to increase the number of supported chains and prios.

2020-01-16net/mlx5e: Add discard counters per priorityAharon Landau
Add counters that count (per priority) the number of received packets that dropped due to lack of buffers on a physical port. If this counter is increasing, it implies that the adapter is congested and cannot absorb the traffic coming from the network.
