Subject: [musl][PATCH 1/2] include/netinet/if_ether.h: define __UAPI_DEF_ETHHDR early
From: Chen Qi <Qi.Chen@...driver.com>
After 'struct ethhdr' is defined, we should immediately define __UAPI_DEF_ETHHDR. Because the following lines are header inclusion lines which might introduce header files checking __UAPI_DEF_ETHHDR.
If we don't define this macro early, we will get redefinition error.
