Hello Parav Pandit,

The patch 87bd418ea751: "net/mlx5: E-Switch, Consider SF ports of
host PF" from Mar 2, 2021, leads to the following static checker
warning:

	drivers/net/ethernet/mellanox/mlx5/core/eswitch.c:1571 mlx5_query_hca_cap_host_pf()
	warn: odd binop '0x0 & 0x1'

                                                       ^^^^^^^^^^^^^^^^^^^^^
HCA_CAP_OPMOD_GET_MAX is zero.
