Synopsis:
#include <qvm/vio.h>void vio_parse_vendor_features(struct vio_vendor_feature *vfeats,
size_t vfeats_size,
char const* vfeats_str)Arguments:
- vfeats
- An array of vdev-provided vio_vendor_feature structures containing feature names and their bit-position fields to mutate.
- vfeats_size
- The size of the vfeats array.
- vfeats_str
- A null-terminated string containing one or more comma-separated name-value pairs indicating
the vendor-specific features and the bit positions where to advertise them.
Each feature name is followed by an equal sign and then the bit position for the feature
