Backport of #16643
Contribution description
Found this while testing #16606: When using the
gnrc_netif_singleoptimization modulegnrc_sockbasically accepts anynetifvalue in thegnrc_sock*_ep_tstructs, as it is just overwritten with the ID only existing network interface. While this seems like a nice extra from a shell user perspective, I wouldn't call this behavior valid and it also might cause some faulty behavior if e.g. invalid interface IDs are received from the network (as might be the case with DHCPv6's Interface ID option #16606).Testing procedure
The following tests should still pass:
