Conflicting definitions of struct ethhdr between the kernel and musl
libc provides headers causes a build failure:
In file included from .../usr/include/netinet/ether.h:8:0,
from useful_functions.c:28:
.../usr/include/netinet/if_ether.h:107:8: error: redefinition of ‘struct ethhdr’
struct ethhdr {
^~~~~~
In file included from include/linux/netfilter_bridge.h:8:0,

from include/ebtables_u.h:27,
from useful_functions.c:25:
include/linux/if_ether.h:119:8: note: originally defined here
struct ethhdr {
^~~~~~
Recent enough versions kernel headers allow the libc to suppress
conflicting kernel definitions. Include the libc proivded
netinet/ether.h before kernel headers to suppress the conflicting
definition of struct ethhdr.
