From 639bf4415cadff4c18e13aa5cb0dba2d443e3aa7 Mon Sep 17 00:00:00 2001 From: Aharon Landau Date: Thu, 17 Sep 2020 12:02:21 +0300 Subject: [PATCH] net/mlx5: Refactor query port speed functions The functions mlx5_query_port_link_width_oper and mlx5_query_port_ib_proto_oper are always called together, so combine them to a new function called mlx5_query_port_oper to avoid duplication. And while the mlx5i_get_port_settings is the same as mlx5_query_port_oper therefore let's remove it. According to the IB spec link_width_oper and ib_proto_oper should be u16 and not as written u8, so perform casting as a preparation to cross-RDMA patch which will fix that type for all drivers in the RDMA subsystem.
