Description

Steps to reproduce the issue

Attach the REB215-XPRO module to the same54-xpro board and flash e.g. gnrc_networking with the at86rf215 module enabled.

Expected results

Sending and receiving works on the 6lo interface

Actual results

Pinging other boards fails. Doing a udp send ff02::1 1234 test works - other boards can receive the message. Messages sent from other boards (after doing a udp server start 1234) are not received.

Versions

git bisect points to 2a255ff as the first bad commit.
With this commit reverted, receiving packets works fine again.
