From 06ec5acc7747f225154fcafaf2afe52324694baa Mon Sep 17 00:00:00 2001 From: Parav Pandit Date: Tue, 2 Mar 2021 13:54:42 +0200 Subject: net/mlx5: E-Switch, Return eswitch max ports when eswitch is supported mlx5_eswitch_get_total_vports() doesn't honor MLX5_ESWICH Kconfig flag. When MLX5_ESWITCH is disabled, FS layer continues to initialize eswitch specific ACL namespaces. Instead, start honoring MLX5_ESWITCH flag and perform vport specific initialization only when vport count is non zero.

Instead of calculating everytime, read directly from eswitch. Additionally, host PF's SF vport information is available using QUERY_HCA_CAP command. It is not available through HCA_CAP of the eswitch manager PF. Hence, this patch prepares the return total eswitch vport count from the existing eswitch struct. This further helps to keep eswitch port counting macros and logic within eswitch.
