Subject: [PATCH mlx5-next 01/10] net/mlx5: Add max_tx_speed and its CAP bit  to IFC

From: Or Har-Toov <ohartoov@...dia.com>

Introduce the max_tx_speed field to the query and modify_vport_state
structures.

Add the esw_vport_state_max_tx_speed capability bit, indicating
the firmware support modifying the max_tx_speed field via the
MODIFY_VPORT_STATE command.
