My servers use rl and bfe devices from deprecated list. Also I have some ed devices for replacement failed adapters. Also I can try do convertion to iflib for bfe, rl and ed devices, but still no one not showed good example driver that has already been converted... P.S. So late, because I was away and just returned.
