Subject: [PATCH net-next V1 03/11] net/mlx4_core: Introduce nic_info new flag in QUERY_FUNC_CAP

From: Hadar Hen Zion <hadarh@...lanox.com>

Set nic_info field in QUERY_FUNC_CAP, which designates
supplementary NIC information is provided by the hypervisor.
When set, the following fields are valid: nic_num_rings,
nic_indirection_tbl_sz, cur_mac and phys_port_id.
