I don't know. Auto-negotiation is optional in 100BASE-TX, so vendors
aren't required to support it. Since these router interfaces are
fixed-speed, perhaps Cisco decided that auto-neg didn't provide enough
value to justify the cost of supporting it. Given the problems caused
by duplex mis-match due to parallel detection, however, I'd like to
see auto-neg support on all ints.
