[L2TP]: Changes to existing ppp and socket kernel headers for L2TP
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. [ Modified to use aligned_u64 in statistics structure -DaveM ] Signed-off-by: James Chapman <jchapman@katalix.com> Signed-off-by: David S. Miller <davem@davemloft.net>
