PPP subsystem MPPE/MPPC support
mpd5 and kernel are missing M$ MPPC/MPPE modules and configureation options.
This would benefit all mpd5 services (pppoe connections, pppoe server, l2tp VPN, and PPTP server)
These are supported by the HIFN hardware accelerators as well, but I am unaware the exact software requirements
This could also be added as a package instead of a core system.
