[PATCH v2 1/4] powerpc/ps3: gelic_udbg: use struct ethhdr from <linux/if_ether.h>

From: Luis Henriques
Date: Mon Feb 08 2016 - 17:27:30 EST


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
