Functions change event output data size changes when functions other than VFs will be enabled in HCA CAP. With current API, multiple callers needs to align, calculate accurate size of the output data depending on number on non VF functions enabled in the device. Instead of duplicating such math at multiple places, refactor mlx5_esw_query_functions() to return raw output allocated by itself. Caller must free the allocated memory using kvfree() as described in the function comment section. This hides calcuation within mlx5_esw_query_functions() and provides simpler API.

Expanding MLX5_TOTAL_VPORTS macro would require exposing SF internals to more generic vport.h header file. Such exposure is not desired. Hence a mlx5_eswitch_get_total_vports() is introduced. Given that mlx5_eswitch_get_total_vports() API wants to work on const mlx5_core_dev*, change its helper functions also to accept const *dev.

2019-07-03IB/mlx5: Fixed reporting counters on 2nd port for Dual port RoCEParav Pandit1-24/+36
Currently during dual port IB device registration in below code flow, ib_register_device() ib_device_register_sysfs() ib_setup_port_attrs() add_port() get_counter_table() get_perf_mad() process_mad() mlx5_ib_process_mad() mlx5_ib_process_mad() fails on 2nd port when both the ports are not fully setup at the device level (because 2nd port is unaffiliated). As a result, get_perf_mad() registers different PMA counter group for 1st and 2nd port, namely pma_counter_ext and pma_counter. However both ports have the same capability and counter offsets. Due to this when counters are read by the user via sysfs in below code flow, counters are queried from wrong location from the device mainly from PPCNT instead of VPORT counters. show_pma_counter() get_perf_mad() process_mad() mlx5_ib_process_mad() process_pma_cmd() This shows all zero counters for 2nd port. To overcome this, process_pma_cmd() is invoked, and when unaffiliated port is not yet setup during device registration phase, make the query on the first port. while at it, only process_pma_cmd() needs to work on the native port number and underlying mdev, so shift the get, put calls to where its needed inside process_pma_cmd().

When driver is doing eswitch mode change, it's critical to keep number of enabled VFs unchanged. However, it can be changed on the fly once function changed event is registered. To remove this uncertainty, function changed event should not be registered before all setups, and first be unregistered before all cleanups. Wrap this functionality together with vport event handler.

2019-07-01net/mlx5: E-Switch, Consolidate eswitch function number of VFsBodong Wang4-88/+90
Enabled number of VFs is key for eswich manager to do flow steering initialization and vport configurations. However, the number of enabled VFs may come from two sources as below. PF: num of VFs is provided by enabled SR-IOV of itself. ECPF: num of VFs is provided by enabled SR-IOV from its peer PF. And SR-IOV can't be enabled from ECPF itself. Current driver handles the two cases in different stages and passing the number of enabled VFs among a large scope of internal functions. It is usually hard to find out where is the real number of VFs from due to layers of argument pass-in. This patch consolidated that number from the entry point of doing eswitch setup, and maintained a copy so that eswitch functions can refer to it directly. Eswitch driver shall always use this number when referring to enabled number of VFs, don't use other numbers such as from SR-IOV.

2019-07-01net/mlx5: E-Switch, Refactor eswitch SR-IOV interfaceBodong Wang10-73/+74
Devlink eswitch mode is not necessarily related to SR-IOV, e.g, ECPF can be at offload mode when SR-IOV is not enabled. Rename the interface and eswitch mode names to decouple from SR-IOV, and cleanup eswitch messages accordingly.

2019-07-01net/mlx5: Handle host PF vport mac/guid for ECPFBodong Wang8-17/+25
When ECPF is eswitch manager, it has the privilege to query and configure the mac and node guid of host PF. While vport number of host PF is 0, the vport command should be issued with other_vport set in this case as the cmd is issued by ECPF vport(0xfffe). Add a specific function to query own vport mac. Low level functions are used by vport manager to query/modify any vport mac and node guid. Signed-off-by: Bodong Wang <bodong@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
