Subject: [PATCH] IPsrcaddr: fixes
- use findif.sh to detect secondary interfaces
- get metric and proto to update the correct route/update it correctly
- match route using interface to fail when trying to update secondary
interfaces without specifying destination (would update default route
before)
- also use PRIMARY_IP/OPTS during stop-action for default routes (to get
back to the exact routes we started with)
- dont fail during stop-action if route doesnt exist
- use [[:blank:]] for WS to follow POSIX standard (suggested by nrwahl)
