The test covers both classes: the PRP LAN-ID race under a netem delay on one slave, and the HSR RedBox source-MAC alias with a tagged multicast on a slave. The capability probes (tc, python3, sch_netem, HSR/PRP support) exit ksft_skip and propagate that status, while real failures exit 1. The capture filters keying on destination, post-strip EtherType and payload while leaving the asserted source MAC unfiltered look correct.
