	Sup1A w/MSFC(1|2) and PFC (EARL5) utilizes classical MLS
(first packet of the flow  are always processed by control plane,
then shortcut is created and subsequent packets are h/w switched
by PFC).

	These sups are based on next-generation PFC2/3B and
performs h/w-based CEF-switching. So there's no MLS here
and you should deal with MLS CEF:

	Default values are pretty OK.
