Detailed Description

struct virtio_chan - per-instance transport information : whether the channel is initialized : whether the channel is in use : protects multiple elements within this structure : client instance : virtio dev associated with this channel : virtio queue associated with this channel : scatter gather list which is used to pack a request (protected?)

We keep all per-channel information in a structure. This structure is allocated within the devices dev->mem space. A pointer to the structure will get put in the transport private.
