Subject: [PATCH] openvswitch: Allow for any level of nesting in flow
 attributes

nlattr_set() is currently hardcoded to two levels of nesting. This change
introduces struct ovs_len_tbl to define minimal length requirements plus
next level nesting tables to traverse the key attributes to arbitrary depth.
