+Subject: [PATCH 1/2] build: support explicitly disabling netcf
+
+placing "-Dnetcf=disabled" on the meson commandline was ignored,
+meaning that even with that option the build would get WITH_NETCF if
+the netcf-devel package was found - the only way to disable it was to
+uninstall netcf-devel.
+
+This patch adds the small bit of logic to check the netcf meson
+commandline option (in addition to whether netcf-devel is installed)
+before defining WITH_NETCF.
