Subject: [PATCH fwctl 2/2] fwctl/mlx5: Add Adjacent function query commands and their scope

From: Saeed Mahameed <saeedm@...dia.com>

MLX5_CMD_OP_QUERY_ADJACENT_FUNCTIONS_ID:
 - Query Adjacent functions (PFs/VFs) of the function calling FW.

MLX5_CMD_OP_DELEGATE_VHCA_MANAGEMENT:
 - Delegates own VFs to be managed/seen by other adjacent PFs

MLX5_CMD_OP_QUERY_DELEGATED_VHCA:
 - Query current function delegation state.
