Subject: [PATCH 2/2] include/netinet/if_ether.h: guard ethhdr definition to better work with other header files
From: Chen Qi <Qi.Chen@...driver.com>
The unconditional definition of 'struct ethhdr' has the implicit
requirement on this header file, that is, it needs to be included
before other header files defining ethhdr.
