Description
In the Linux kernel, the following vulnerability has been resolved:
idpf: fix kernel panic on unknown packet types
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.
