-Subject: [PATCH 3/3] uapi/if_ether.h: prevent redefinition of struct ethhdr
+Subject: uapi/if_ether.h: prevent redefinition of struct ethhdr
 
 Musl provides its own ethhdr struct definition. Add a guard to prevent
 its definition of the appropriate musl header has already been included.

+glibc does not implement this header, but when glibc will implement this
+they can just define __UAPI_DEF_ETHHDR 0 to make it work with the
+kernel.
