Chris,

The RSS option was updated a while back to control the number of queues
that a workload can be distributed over in a non-DCB mode.  Setting it
to 0 is only going to give you one queue per port.

If you are wanting the behaviour to be that all non-filtered traffic
goes to queue 0 your best option would be to modify the driver so that
all writes to IXGBE_RETA(x) are nothing but 0.  This would force all
non-filtered to be dropped into queue 0.

Thanks,

Alex
