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.
