The test in configure checks for struct mmsghdr in sys/socket.h,
but actual source (net/l2tpv3.c) includes a linux-specific header,
linux/ip.h.  This fails on at least kFreeBSD (Debian with FreeBSD
header and glibc), because glibc declares mmsghdr but does not
provide linux/ip.h.

Probably the configure test should also include this linux-specific
header.  At least this is what I plan to do to fix the build failure
with 2.1.

Thanks,
