I've compiled xl2tpd with debug symbols and without optimizations and
run it in gdb with "-D". In network.c, function network_thread(), the
select() call returns when the packet is received on ipsec0. The
FD_ISSET(server_socket, &readfds) is true. However, the recvmsg call in
line 430 does return -1 and errno is EAGAIN.
There must be something going very wrong or is this a fragmentation problem?
