Subject: [PATCH] default gateway regex: use exact match for iface name

If the current interface has a default gateway configured is
determined by the regex

  default.+<interface-name>

If for example 'enc1' is used, but also an interface 'enc1800' is
present, the regex will also match the 'enc1800' default gateway.

This patch fixes this by looking for <interface-name><white-space>.
This way 'enc1800' is not matched.
