Unfortunately, this breaks the build for musl toolchains. Both the autoconf
test and the actual code in src/libnet_link_linux.c have stupid __GLIBC__ checks which make it include linux/if_ether.h instead of the toolchain header, and that triggers a failure because of multiple definitions. The fundamental solution is to add AC_CHECK_HEADERS of netinet/if_ether.h and act accordingly. But for me it's sufficient to just make it:

# PF_PACKET is always available on Linux, but build breaks for musl ifneq ($(BR2_TOOLCHAIN_USES_MUSL),y)
LIBNET_CONF_OPTS = libnet_cv_have_packet_socket=yes endif

Regards,
Arnout
