This patch updates libmodbus from version 2.0.3 to the latest stable release 3.0.2 I needed modbus RTU and that seemed to be missing in the older version ? Patch is also attached in case it is corrupt inline here! Signed-off-by: Simon Gaynor <openwrt@simong.net> git-svn-id: svn://svn.openwrt.org/openwrt/packages@31099 3c298f89-4303-0410-b956-a3cf2f4a3e73
