Subject: Re: iproute2: make ip route list to search by metric too
Hello again,
Things turned out to be not so hard. Please take a look at the attached patch.
I'm only not sure if RTA_PRIORITY is enough. Because the print_route
function prints "metric" also for some situations with RTA_METRICS,
which I haven't managed to understand.
