> Subject: [Intel-wired-lan] [PATCH iwl-net] idpf: fix kernel panic on unknown
> packet types
>
> From: Joshua Hay <joshua.a....@intel.com>
>
> In the very rare case where a packet type is unknown to the driver,
> idpf_rx_process_skb_fields would return early without calling
> eth_type_trans to set the skb protocol / the network layer handler.
> This is especially problematic if tcpdump is running when such a
> packet is received, i.e. it would cause a kernel panic.
>
> Instead, call eth_type_trans for every single packet, even when
> the packet type is unknown.
