From b06e7de8a9d8d1d540ec122bbdf2face2a211634 Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Tue, 23 Feb 2016 10:25:22 +0200 Subject: net/mlx5_core: Refactor device capability function Device capability function was called similar in all places. It was called twice for every queried parameter, while the difference between calls was in HCA capability mode only. The change proposed unify these calls into one function.

Also update current users of the API. PFs may call mlx5_core_query_vport_counter with other_vport set to indicate that they are querying a virtual function. The virtual function to be queried is given by the vf parameter. Virtual function numbering is zero based so the first VF is 0 and so on. When a PF queries its own function, the other_vport parameter is cleared.

This functionality is added into a new file that will be used to add any SRIOV related functionality to the mlx5 IB layer. The following callbacks have been added: mlx5_ib_get_vf_config mlx5_ib_set_vf_link_state mlx5_ib_get_vf_stats mlx5_ib_set_vf_guid In addition, publish whether this device is based on a virtual function. In mlx5 supported devices, virtual functions are implemented as vHCAs. vHCAs have their own QP number space so it is possible that two vHCAs will use a QP with the same number at the same time.
