Subject: [PATCH RFC net-next] net/vxlan: Fix kernel unaligned access in __vxlan_find_mac
Date: Fri, 17 Jul 2015 13:07:31 +0200 [thread overview]
Message-ID: <20150717110731.GA30336@oracle.com> (raw)
__vxlan_find_mac invokes ether_addr_equal on the eth_addr field,
which triggers unaligned access messages, so rearrange vxlan_fdb
to avoid this as non-intrusively as possible.
