Specifically, vpp-3n-icx-100ge2p1e810cq-avf-srv6-78b-1c-ethip6ip6-ip6base-srv6enc1sid-mrr
shows [0] two band structure even though it does not fit other known possible causes of two-band structure (RSS should be deterministic for AVF, SRv6 is not using qemu or other virtual interfaces in the need of pinning).
Also, other SRv6 test cases do not have as large standard deviation, so explain why.
