There is a trivial conflict with Thomas' validate PDU length patch, but as it is trivial either work for me - pick whichever is easier to work with for you. The main reason I asked for a new version of the other patch is that the IDR rework changed spin locks, so I'd rather it being clean. Thanks, -- Dominique
