For some reason 5/7 and 6/7 didn't get delivered to me (although they are in the list archive). I have a suggestion for slight rewording of the function description in 5/7, which I'll list here, but otherwise ACK for the series.


* Turn the IFF_VNET_HDR flag, if requested and available, make sure it's
* off in the other cases. Similarly, IFF_MULTI_QUEUE is enabled if
* requested. However, if requested and failed to set, it is considered a
* fatal error (as opposed to @vnet_hdr).

Instead maybe:

  "Turn on the IFF_VNET_HDR flag if requested and available, but make sure
  it's off otherwise. Similarly, turn on IFF_MULTI_QUEUE if requested, but
  if it can't be set, consider it a fatal error (rather than ignoring as
  with @vnet_hdr)."
