Subject: [PATCH 0/4] Conditionally read fields in dev cfg space
This series intends to read the fields in virtio-net device
configuration space conditionally on the feature bits,
this means:
MTU exists if VIRTIO_NET_F_MTU is set
MAC exists if VIRTIO_NET_F_NET is set
MQ exists if VIRTIO_NET_F_MQ or VIRTIO_NET_F_RSS is set.
This series report device features to userspace and invokes
vdpa_config_ops.get_config() than vdpa_get_config_unlocked()
to read the device config spcae, so no raeces in
vdpa_set_features_unlocked()
Thanks!
Zhu Lingshan (4):
vDPA: allow userspace to query features of a vDPA device
vDPA: only report driver features if FEATURES_OK is set
vDPA: check VIRTIO_NET_F_RSS for max_virtqueue_paris's presence
vDPA: Conditionally read MTU and MAC in dev cfg space
