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

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
