By the way, the LASI registers are already named in <linux/mdio.h>:

#define MDIO_PMA_LASI_RXCTRL	0x9000	/* RX_ALARM control */
#define MDIO_PMA_LASI_TXCTRL	0x9001	/* TX_ALARM control */
#define MDIO_PMA_LASI_CTRL	0x9002	/* LASI control */
#define MDIO_PMA_LASI_RXSTAT	0x9003	/* RX_ALARM status */
#define MDIO_PMA_LASI_TXSTAT	0x9004	/* TX_ALARM status */
#define MDIO_PMA_LASI_STAT	0x9005	/* LASI status */
