    The patch below implements the Microsoft Point-to-Point Encryption method
    as a PPP compressor/decompressor. This is necessary for Linux clients and
    servers to interoperate with Microsoft Point-to-Point Tunneling Protocol
    (PPTP) servers (either Microsoft PPTP servers or the poptop project) which
    use MPPE to encrypt data when creating a VPN.

    This patch differs from the kernel_ppp_mppe DKMS pacakge at
    pptpclient.sourceforge.net by utilizing the kernel crypto routines rather
    than providing its own SHA1 and arcfour implementations.

    Minor changes to ppp_generic.c try to prevent a link from disabling
    compression (in our case, the encryption) after it has started using
    compression (encryption).

    Feedback to please.
