[c-nsp] 7513 - RSP4 - 122-25.S15 - MLPPP / Dcef Weirdness

[Rodney Dunn]

The two games in town for 75xx will be:

12.0(32)S(x) rebuild -- more HA features

12.4(latest) mainline until full EoS for the platform.


I wouldn't recommned any other train at this point for the platform
even if the code is available.
