+Patch reverts upstream commit:
+https://github.com/collectd/collectd/commit/6124da7a48f28f54fc09ebeb942d1037516fe6ab
+
+The commit changed the detection path due to FreeBSD issues,
+but apparently affects also Openwrt buildroot negatively.
+
+Original explanation:
+ From 6124da7a48f28f54fc09ebeb942d1037516fe6ab Mon Sep 17 00:00:00 2001
+ Subject: [PATCH] Fix libmodbus detection on FreeBSD
+
+ We look for modbus/modbus.h in /usr/local/include/modbus
+ but we should look for modbus.h
+
+ This is only an issue on FreeBSD since /usr/local/include is not
+ in the default search path.
