[c-nsp] CEF problems 6509-E SUP720

[Church, Charles]

There was a PSIRT just released last week that talked about
vulnerabilities of the loopback addresses used in the EOBC on the 65/76
devices.  Maybe someone is trying to take advantage of it, and CEF
doesn't like trying to create an entry for it.  Just a guess though.

Anyone got any idea what this might be?
