"case='network'" currently <em>only</em> support single IP/hostname. Therefore, easy fix would be to either not permit multiple ip when case=network. So it does not fail. (This is what this patch intended to do). Further, Update doc pdf.</p> <p>3. Major improvement to make it accept multiple IP (improve iokit-libecho/setup_srv_obd), which this patch does not target.</p> Duplicate Development Rank 1|hzzasf: Rank (Obsolete) 9223372036854775807 Severity
