Introduced a new command-line interface (CLI) command “[no] bfrp
carve-level [0 | 1]” to enable or disable packet buffer recarve optimization.
The packet buffer recarving occurs when an MTU (maximum transmission
unit) is changed on the router.

The bug id caveat CSCso80492 introduced a behavioral change to the
carve-level 1 mechanism. After changing the largest MTU configured on
a slot, sometimes an extra buffer queue is added in the ToFab of other line
cards. This additional of an extra buffer queue that is not in the global
buffer distribution (dsn) is used to process packets that enter its range.
