Yes, it might require holding off the other patches until net is

Packet sockets are likely not the only way these packets are received?
It changes mac_len as computed in __netif_receive_skb_core.

I looked at __netif_receive_skb_core. I didn't see it computing mac_len?

I thought only AF_PACKET/RAW sockets would need this information
because other upper layers would not care about what happened in L2.

I see mac_len is computed in netif_receive_generic_xdp. I'm not clear
about the reason why it calculates it. But it seems that it considers
the L2 header as an Ethernet header, which is incorrect for this
driver.

If there is no real bug that is fixed, net-next is fine.
