+Subject: [PATCH] vrrp: Don't include <linux/if_ether.h> if not needed
+
+The musl headers do not allow including both <linux/if_ether.h> and
+<net/ethernet.h> since they both define struct ethhdr.
+
+It is likely that we do not need to include <linux/if_ether.h> at all
+since with both glibc and musl including  <net/ethernet.h> is sufficient,
+but removing <linux/if_ether.h> is for another day.
+
