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/linux/netfilter_bridge/ebtables.h:17, 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.
