OpenWrt Package for xl2tpd

xl2tpd is a development from the original l2tpd package originally written by Mark Spencer, subsequently forked by Scott Balmos and David Stipp, inherited by Jeff McAdams, modified substantially by Jacco de Leeuw and then forked again by Xelerance (after it was abandoned by l2tpd.org).

Rationale for inclusion in OpenWrt

l2tpd has some serious alignment problems on RISC platforms. It also runs purely in userspace.

Some of the features added in this fork include:

1. IPSec SA reference tracking inconjunction with openswan's IPSec transport mode, which adds support for multiple clients behind the same NAT router and multiple clients on the same internal IP behind different NAT routers.

2. Support for the pppol2tp kernel mode L2TP.

3. Alignment and endian problems resolved.

UCI options

server takes the form host[:port] with port defaults to 1701. It specifies the l2tp server's address.

checkup_interval tells netifd to check after that many seconds since last setup attempt to see if the interface is up. If not it should issue another teardown/setup round to retry the negotiation. This option defaults to 0 and netifd will not do the check and retry.

The following are generic ppp options and should have the same format and semantics as with other ppp-related protocols. See uci/network#protocol_ppp for details.
