Subject: [net-next 04/14] net/mlx5e: HTB, reduce visibility of htb functions
From: Saeed Mahameed <saeedm@...dia.com>
No need to expose all htb tc functions to the main driver file,
expose only the master htb tc function mlx5e_htb_setup_tc()
which selects the internal "now static" function to call.
