Subject: iproute2: detect iptables modules dir in configure.
X-Git-Url: https://rtime.felk.cvut.cz/gitweb/lisovros/iproute2_canprio.git/commitdiff_plain/12ddfff76ca4a373d50fd2ac7fff2bd4e0883955

iproute2: detect iptables modules dir in configure.

Try to automatically detect iptables modules directory.

Make the configure script look for iptables modules.
This also makes it possible to specify it on the
command line while building via "make IPT_LIB_DIR=/foo/bar".
