iproute2 add hoplimit parsing and update usage and documentation
- Parse and handle the hoplimit ip route option and add it to the usage
line and documentation.
- Add the missing reordering ip route option to the usage line.
- Add documentation for initcwnd ip route option.
Tested by setting hoplimit and retreiving it via "show".
