Subject: [iptables][PATCHv2] configure: Add option to enable/disable libnfnetlink
Date: Thu, 25 Apr 2024 10:51:02 +0200 [thread overview]
Message-ID: <20240425085102.3528036-1-alex@linutronix.de> (raw)
From: "Maxin B. John" <maxin.john@intel.com>
Default behavior (autodetecting) does not change, but specifying
either option would explicitly disable or enable libnfnetlink support,
and if the library is not found in the latter case, ./configure will error
out.
