That's exactly what happened.
The 2.4.6 kernel now defines SIOCGMIIPHY, but not the ioctl(SIOCSPARAMS)
call that sets parameters such as the interrupt mitigation value (on the
tulip) and debug level (on certain drivers).

The work-around is to add an #endif/#ifdef to the kern_compat.h file

#define SIOCGMIIPHY (SIOCDEVPRIVATE)		/* Get the PHY in use. */
#define SIOCGMIIREG (SIOCDEVPRIVATE+1) 		/* Read a PHY register. */
#define SIOCSMIIREG (SIOCDEVPRIVATE+2) 		/* Write a PHY register. */
#define SIOCGPARAMS (SIOCDEVPRIVATE+3) 		/* Read operational parameters. */
#define SIOCSPARAMS (SIOCDEVPRIVATE+4) 		/* Set operational parameters. */

Could you please try this?
