Macros that refer to local variables are nasty.  qdev should be a macro
parameter.  __FUNCTION__ (gcc extension) should be replaced with __func__
(C99).  Finally, this should call dev_printk() - something like this:

#define QPRINTK(qdev, nlevel, klevel, fmt, args...)		\
	if (!((qdev)->msg_enable & NETIF_MSG_##nlevel))		\
		;						\
	else							\
		dev_printk(KERN_##klevel, &((qdev)->pdev->dev),	\
			   "%s: " fmt, __func__, ##args)

Ew, no.  You should use __packed at the end of each structure definition.
