maple_devinfo_t	info
	Device info struct.
maple_frame_t	frame
	One rx/tx frame.
struct maple_driver *	drv
	Driver which handles this device.
uint8	probe_mask
	Mask of sub-devices left to probe.

volatile uint8	status_valid
	Have we got our first status update?
uint32	status []
	Status buffer (for pollable devices)

Detailed Description

One maple device.

Note that we duplicate the port/unit info which is normally somewhat implicit so that we can pass around a pointer to a particular device struct.
