Here comes two main parts, one is ifcvf_base layer, which handles hardware operations. The other is ifcvf_main layer handles VF initialization, configuration and removal, which depends on and complys to: virtio_mdev https://lkml.org/lkml/2019/10/30/62 vhost_mdev https://lkml.org/lkml/2019/10/31/440 This patchset passed netperf tests. This is RFC V2, plese help review. Changes from V1: using le32_to_cpu() to convert PCI capabilities. some set /get operations will sync with the hardware, eg get_status and get_generation. remove feature bit VHOST_F_LOG_ALL, add VIRTIO_F_ORDERED_PLATFORM add get/set_config functions. split mdev type group into mdev_type_group_virtio and mdev_type_group_vhost add ifcvf_mdev_get_mdev_features() coding stype changes.
