Add max_supported_vqs and supported_features fields to struct
vdpa_mgmt_dev. Upstream drivers need to feel these values according to
the device capabilities.
These values are reported back in a netlink message when showing management
devices.
Examples:
$ auxiliary/mlx5_core.sf.1:
supported_classes net
max_supported_vqs 257
dev_features CSUM GUEST_CSUM MTU HOST_TSO4 HOST_TSO6 STATUS CTRL_VQ MQ \
CTRL_MAC_ADDR VERSION_1 ACCESS_PLATFORM
$ vdpa -j mgmtdev show
{"mgmtdev":{"auxiliary/mlx5_core.sf.1":{"supported_classes":["net"], \
"max_supported_vqs":257,"dev_features":["CSUM","GUEST_CSUM","MTU", \
"HOST_TSO4","HOST_TSO6","STATUS","CTRL_VQ","MQ","CTRL_MAC_ADDR", \
"VERSION_1","ACCESS_PLATFORM"]}}}
$ vdpa -jp mgmtdev show
{
"mgmtdev": {
"auxiliary/mlx5_core.sf.1": {
"supported_classes": [ "net" ],
"max_supported_vqs": 257,
"dev_features": ["CSUM","GUEST_CSUM","MTU","HOST_TSO4", \
"HOST_TSO6","STATUS","CTRL_VQ","MQ", \
"CTRL_MAC_ADDR","VERSION_1","ACCESS_PLATFORM"]
}
}
}
