Defect Description:
	PHNE_29988:
	1. CR:JAGae76737 SR:8606313961
	   A lanadmin(1M) reset on an EISA Token Ring interface
	   causes the system to panic. This problem happens because
	   the EISA Token Ring driver acquires and holds a lock
	   across subsystems, when notifying link status.
	Resolution:
	   EISA Token Ring driver has been modified to release
	   the lock before calling the function to notify link
	   status.

Enhancement:
	No
