If one target address is not local and its route is different than
default gateway, the specific route to this target address need be
added. E.g, target is 192.168.200.222.
sh> ip route show
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
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 semicolon like below. Then the stored
route can be parsed when kdump kernel boot up.
192.168.200.0/24:192.168.100.222:ens10

Looks good to me.
Thanks Bao. Static route support is important one.
