Patch for ROUTE from FreeBSD.

ignore errors + batch mode

Adds '-f' switch, which loads set of commands from file. So you can make multiple updates of routing table with single call to route. Each line of file contains single route command. For example:

cmd line

route -f route.rules

route.rules

add 10.0.0.0/24 192.168.0.1
add 10.0.1.0/24 192.168.0.1
change 10.0.2.0/24 192.168.0.2

Also adds '-i' switch to command line. When '-i' is used, all routing commands containing errors will be rejected, but correct commands will be applied. ROUTE shall not stop on the 1st invalid command. It is useful when loading routing rules from file.

route -i -f route.rules
