If one target address is not local and its route is different than

added.
In this patch, get the route to the specific target address and store
it as cmdline, here is /etc/cmdline.d/45-route-static.conf. And the
route options are separated by underscore like below. Then the sotred
route can be parsed when kdump kernel boot up.
192.168.200.0/24_via_192.168.100.222_dev_ens10
I think it is a good idea to quote one example of "ip route show" where
there is one default route setting and one static route setting. I noticed
that you gave an example to Harald in your mail conversation.
default via 192.168.122.1 dev eth0 proto static metric 1024
192.168.200.0/24 via 192.168.100.222 dev ens10 proto static metric 1
Also, has harald accepted your patch. Has things been sorted out with
him for syntax of rd.route option?
Thanks
Vivek
