Instead of defining a local version of struct ethhdr use the standard
definition from <linux/if_ether.h>.
The fields in the <linux/if_ether.h> definition have different names:
- dest -> h_dest
- src -> h_source
- type -> h_proto
While there, use a few other standard functions/macros:
- eth_broadcast_addr (instead of a memset)
- ETH_ALEN
- ETH_P_8021Q
