Subject: [PATCH] zeroconf: Rename arp_op to avoid namespace conflicts with C
 library

on musl e.g. we get
In file included from /mnt/a/oe/build/tmp/work/corei7-64-bec-linux-musl/zeroconf/0.9-r1/recipe-sysroot/usr/include/net/ethernet.h:10:0,

This is because in musl arp_op is a define which is included
and causes the conflict
