Re: [PATCH net v3 4/4] selftests: net: hsr: add GRO super-packet forwarding test

[Ali Ahmet Memis]

I ran this under virtme-ng (QEMU/KVM). It passes on the patched kernel:
the SAN TX frame-size average is around 41 kB, well over the 2048 byte
threshold, both DUT LAN legs average around 1497 bytes, under the 1514
byte guard, and it reports success. On an unpatched kernel it correctly
fails, where oversized HSR-tagged frames reach the LAN legs, so the test
discriminates the fix. The topology setup and the counter delta
thresholds look sound.
