Jonas,
this is ethernet-ccc specific. Usually with vlan-ccc you switch
the traffic from one vlan to another vlan without looking at
what is inside. Once you terminate a whole ethernet stream with
ae we have to look at each and see if we find LACP which has to
be send up to the RE. This additional check induces additional
micro-code instructions and space on the incoming FPC.
Enhanced FPCs have more micro-code space.
