Subject: [PATCH net-next] selftests: fib_nexthops: Make ping timeout configurable
Commit 49bb39bddad2 ("selftests: fib_nexthops: Make the test more robust")
increased the timeout of ping commands to 5 seconds, to make the test
more robust. Make the timeout configurable using '-w' argument to allow
user to change it depending on the system that runs the test. Some systems
suffer from slow forwarding performance, so they may need to change the
timeout.
