NetApp filers consider this to be a legitimate configuration, even a
"supported and recommended one".  If I understand the documentation
correctly, NetApp will (somehow) remember the physical interface a
request arrived on, and make sure to its send replies out same.  It
sounds like a slight breakage of the expected behavior in order to
gain load-sharing for their multiple NICs attached to the same subnet.
 IIRC, you can turn the feature off if it makes an issue.
