Description (partial)

Engine 3 Tcam Carving Config does not get restored and the config gets errored out with the following error after reload: 
 !!% 'tcam-rm' detected the 'fatal' condition 'TCAM-RM: Only Engine 3 cards
      support tcam carving.'

Error is seen only on RP is because that is where the verifier is run. But the single, rather than multiple errors, is the clue. Code inspection of tcam_rm_carve_verify_func() finds that the entire verification batch is aborted when an error is seen. So, if slot X has the error (i.e. because it is not present), the entire batch will fail, including config for any other slots.
