[f-nsp] CER: IPv6 Route ADD: CAM entry creation FAILED

[Brian Rak]

None of the cam-partition commands are even supported on the CER, so I'm 
not sure how to even begin to look at utilization.  The only real 
commands related to this are 'show cam l4 SLOT/PORT', which doesn't 
really tell me a whole lot.

I've checked that our route counts are below what we have defined in 
system-max... if there's another limit here it's not well documented.
