Subject: Fix building on systems with musl (#10)
X-Git-Tag: v8.1.2~46
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=73e19e9886f1e2493d049327a5c853cd975d5a7d;p=thirdparty%2Fdhcpcd.git

Fix building on systems with musl (#10)

musl has its own definition of struct ethhdr, so only include
netinet/if_ether.h on systems with GLIBC.  For the ARPHDR constants, we
must include linux/if_arp.h instead.
