net/mlx5_core: Break down the vport mac address query function
Introduce a new function called mlx5_query_nic_vport_context(). This function gets all the NIC vport attributes from the device. The MAC address is just one of the NIC vport attributes, so mlx5_query_nic_vport_mac_address() is now just a wrapper function above mlx5_query_nic_vport_context(). More NIC vport attributes will be used in following commits. Signed-off-by: Achiad Shochat <achiad@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
