ipath_get_faststats - get word counters from chip before they overflow - contains a pointer to the infinipath device ipath_devdata

called from add_timer

u64 ipath_snap_cntr	(	struct ipath_devdata *	dd,
		ipath_creg	creg
	)

ipath_snap_cntr - snapshot a chip counter : the infinipath device : the counter to snapshot

called from add_timer and user counter read calls, to deal with counters that wrap in "human time". The words sent and received, and the packets sent and received are all that we worry about. For now, at least, we don't worry about error counters, because if they wrap that quickly, we probably don't care. We may eventually just make this handle all the counters. word counters can wrap in about 20 seconds of full bandwidth traffic, packet counters in a few hours.
