Subject: [net-next 04/15] net/mlx5: fs, make get_root_namespace API function

From: Saeed Mahameed <[email-masked]>
Date: Wed, 11 Sep 2024 13:17:46 -0700

From: Moshe Shemesh <[email-masked]>

As preparation for HW Steering support, where the function
get_root_namespace() is needed to get root FDB, make it an API function
and rename it to mlx5_get_root_namespace().
