Subject: l2tpv3 (configure): it is linux-specific
X-Git-Tag: v2.1.1~47
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e22d5dc07350b81006ca6b9bf5fd7b517e2574ee;p=thirdparty%2Fqemu.git

l2tpv3 (configure): it is linux-specific

Some non-linux systems, for example a system with
FreeBSD kernel and glibc, may declare struct mmsghdr
(in glibc) but may not have linux-specific header
file linux/ip.h.  The actual implementation in qemu
includes this linux-specific header file unconditionally,
so compilation fails if it is not present.  Include
this header in the configure test too.
