tests: gnrc_ipv6_ext_frag crashes #21931
Description
Description
Currently, the test for gnrc_ipv6_ext_frag is crashing in master.
Steps to reproduce the issue
sudo dist/tools/tapsetup/tapsetup
make -C tests/net/gnrc_ipv6_ext_frag/ -j clean flash test-as-root
(remember to clear your firewall for the tap interfaces, otherwise the test will outright fail after the unittests ;-))
It helps to apply the following patch
diff --git a/tests/net/gnrc_ipv6_ext_frag/tests-as-root/01-run.py b/tests/net/gnrc_ipv6_ext_frag/tests-as-root/01-run.py
