Subject: [PATCH net 3/5] openvswitch: Fix ovs_dp_cmd_msg_size()

From: Daniele Di Proietto <>

commit 43d4be9cb55f3bac5253e9289996fd9d735531db (openvswitch: Allow user space
to announce ability to accept unaligned Netlink messages) introduced
OVS_DP_ATTR_USER_FEATURES netlink attribute in datapath responses,
but the attribute size was not taken into account in ovs_dp_cmd_msg_size().
