Unfortunately I haven't had time to check if EM_MULTIQUEUE suffers from a regression with iflib – previous em-attached NICs 2nd queue support. At least one i217 I'm using -current with, uses only one queue. But that was igb, not em, so I'm wondering if i217 ist limited to 1 queue – at least i210 supports 4 queues... hints welcome. But I have several oldish machines with hartwell (82574L, still running 10-stable), which showed much better delivery if multiple line speed clients were generating load and EM_MULTIQUEUE added support for 2 queues (and ULE on SMP machine...). I'm also unsure about the current netmap state. When I last checked (some months ago), igb(->em)/netmap didn't work. If netmap support was restored, I missed that. Can you confirm that if EM_MULTIQUEUE and netmap are supposed to be still working with all the adapters which were supported by previous stable-11 (em+igb) code? Or do we need bold release notes that igb/em users must be aware of significant changes? Thanks, -harry
