    [L2TP]: Changes to existing ppp and socket kernel headers for L2TP · cf14a4d0
    James Chapman authored
    Add struct sockaddr_pppol2tp to carry L2TP-specific address
    information for the PPPoX (PPPoL2TP) socket. Unfortunately we can't
    use the union inside struct sockaddr_pppox because the L2TP-specific
    data is larger than the current size of the union and we must preserve
    the size of struct sockaddr_pppox for binary compatibility.
    
    Also add a PPPIOCGL2TPSTATS ioctl to allow userspace to obtain
    L2TP counters and state from the kernel.
    
    Add new if_pppol2tp.h header.
