Introduce SF support. Similar to VF, SF on auxiliary bus is a portion of hardware PF, no representor or bonding parameters for SF. Devargs to support SF: -a auxiliary:mlx5_core.sf.8,dv_flow_en=1 New global syntax to support SF: -a bus=auxiliary,name=mlx5_core.sf.8/class=eth/driver=mlx5,dv_flow_en=1 Signed-off-by: Xueming Li <xuemingl@nvidia.com> Acked-by: Viacheslav Ovsiienko <viacheslavo@nvidia.com>
