Hi Boyan, I followed up on the NFQUEUE case on 26 Oct, in this reply to the v3: https://lore.kernel.org/netdev/20261026003415.f7c46fa5a495144c29c03a07@uniroma2.it/ > My understanding is that NFQUEUE is the remaining open question > for v3.

As I wrote there, setting the mac header at the network header with mac_len 0 looks fine, and the reported crash is gone with v3 in my tests. The NFQUEUE case in the Sashiko review also exists without this patch, so it is not introduced by v3. On the SRv6 side, I think the current approach is acceptable, and the NFQUEUE case can be handled separately. Ciao, Andrea
