NAME
       eth_type_trans - determine the packet's protocol ID.

SYNOPSIS
       __be16 eth_type_trans(struct sk_buff * skb, struct net_device * dev);

ARGUMENTS
       skb
           received socket data

       dev
           receiving network device

DESCRIPTION
       The rule here is that we assume 802.3 if the type field is short enough to be a length.
       This is normal practice and works for any 'now in use' protocol.
