[PATCH v3] fix the corner case of static route
Previously for fixing the static route problem, all routes get through
a specific network interface will be saved and added in 2nd kernel.
Search pattern is used to get routes:
/sbin/ip route show | grep -v default | grep "^[[:digit:]].*via.* $_netdev"
An exception existed though, that is 2 machines connected directly and the
network interfaces wihch are configured as in different network subnets.
So in the v1 and v2, "ip route get to $target" command is executed and an
exact route to a target is saved and added in 2nd kernel. This works for
static route issue and can fix the corner case above.
v1:
Introduced the new way which get exact route to remote target.
v1->v2:
Since a grammer error which saved exact route, v2 is posted.
v2->v3:
Per Vivek's comment, route to target should not be related to
static ip issues. So in v3 introduced the get_routes function
and take it out of kdump_static_ip.
