[git commit] arping: fix iface name in error messages

[Denys Vlasenko]

commit: http://git.busybox.net/busybox/commit/?id=748fb60f274b1ba40aa6ed4c4582185aae8f68f7

arping: interface eth0 not found: No such device
                  ^^^^

This is because error template is formed before parsing command line arguments,
so it always uses default interface name "eth0".
