Contribution description

This fixes an issue of the addresses on the Ethernet interface of a border router never becoming valid.

Testing procedure

Flash a 6Lo-capable board (e.g. samr21-xpro) with gnrc_border_router. The Ethernet interface should now (check with ifconfig) have a valid address (signified by VAL instead of TNT[1]).

Issues/PRs references

Reported in #10817 (comment).

Even though it works with ESP32 border router, we should wait for a test with other boards

Then rather not block but just dismiss your review ;-)

Not that I really understand/checked what make it works, but indeed the address is now VAL and not TNT[1] anymore.

I ran
