vdpa_sim_net: support feature provisioning
This patch implements features provisioning for vdpa_sim_net.
1) validating the provisioned features to be a subset of the parent
features.
2) clearing the features that is not wanted by the userspace
For example:
vdpasim_net:
supported_classes net
max_supported_vqs 3
dev_features MTU MAC CTRL_VQ CTRL_MAC_ADDR ANY_LAYOUT VERSION_1 ACCESS_PLATFORM
1) provision vDPA device with all features that are supported by the
net simulator
dev1: mac 00:00:00:00:00:00 link up link_announce false mtu 1500
negotiated_features MTU MAC CTRL_VQ CTRL_MAC_ADDR VERSION_1 ACCESS_PLATFORM
2) provision vDPA device with a subset of the features
dev1: mac 00:00:00:00:00:00 link up link_announce false mtu 1500
negotiated_features CTRL_VQ VERSION_1 ACCESS_PLATFORM
