From b753af31abe416b19830d5ac7f8da6c16f165214 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Mon, 2 Mar 2015 00:01:30 -0600 Subject: [PATCH] rose: Set the destination address in rose_header Not setting the destination address is a bug that I suspect causes no problems today, as only the arp code seems to call dev_hard_header and the description I have of rose is that it is expected to be used with a static neigbour table. I have derived the offset and the length of the rose destination address from rose_rebuild_header where arp_find calls neigh_ha_snapshot to set the destination address.
