[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.

/***************************************************************************
* Linux PPP over L2TP (PPPoL2TP) Socket Implementation (RFC 2661)
*
* This file supplies definitions required by the PPP over L2TP driver
l2tp: Split pppol2tp patch into separate l2tp and ppp parts This patch splits the pppol2tp driver into separate L2TP and PPP parts to prepare for L2TPv3 support. In L2TPv3, protocols other than PPP can be carried, so this split creates a common L2TP core that will handle the common L2TP bits which protocol support modules such as PPP will use. Note that the existing pppol2tp module is split into l2tp_core and l2tp_ppp by this change. There are no feature changes here. Internally, however, there are significant changes, mostly to handle the separation of PPP-specific data from the L2TP session and to provide hooks in the core for modules like PPP to access.

net/l2tp: add support for L2TP over IPv6 UDP Now that encap_rcv() works on IPv6 UDP sockets, wire L2TP up to IPv6. Support has been tested with and without hardware offloading. This version fixes the L2TP over localhost issue with incorrect checksums being reported. Signed-off-by: Benjamin LaHaise <bcrl@kvack.org> Signed-off-by: David S. Miller <davem@davemloft.net>
