- add option to enable libipq build
- as libipq.h includes linux/netfilter_ipv4/ip_queue.h install (not
provided by modern kernels otherwise?)

- use src-nrlsmf-with-protolib-1.1b2a.tgz download (instead of plain
git one) with bundled protolib as nrlsmf does not compile with an
up to date protolib version
- needs thread support (pthread.h)
- select BR2_PACKAGE_IPTABLES_LIBIPQ to gain access to
header linux/netfilter_ipv4/ip_queue.h
- overwrite CFLAGS to re-add nrlsmf specific include paths and
defines (taken from unix/Makefile.common and unix/Makefile.linux)
- add -fpmerissive to avoid build error
- overwrite SYSTEM_LIBS to avoid libpcap linking
- overwrite CC to link usign g++ (instead of gcc, fixes linking
error because of missing C++ libs)

Is it really a good idea to add an option for this library?
Debian dropped installing libipq 5 years ago, as this library is
deprecated:
https://salsa.debian.org/pkg-netfilter-team/pkg-iptables/-/commit/bf21537d27ee72cc69ca0883059b315ceaf9737d
Also in 2012, iptables developers said they would keep this library for
1.5-2 years:
https://git.netfilter.org/iptables/commit/?id=a624e0a1b2d075253b599ababd4ea1351ef42b2a
But then, when I look at the nrlsmf source code, I don't see any
reference to libipq or ip_queue.h. Am I missing something ?
Thanks,
Thomas

Did the patch as part of porting an custom (very ancient ubuntu based) project
to up-to-date buildroot, but hope to get rid of all legacy dependencies on the
long run..., no problem with dropping this patch...

File smf-1.1b2/protolib/unix/linuxDetour.cpp:
15 #include <linux/netfilter_ipv4/ip_queue.h>
Mhhh, maybe I mistake it because of the ip_queue.h file found in libipq...
No problem dropping this patch, see above ;-)
Regards,
Peter
