  When set port DCB mode enabled, it should remove RSS HASH offload
before reconfiguring the device and queues.

Because port multi-queue mode is changed from RSS to DCB.

I think this change will effect DCB_ENABLED case also ( without VT). In 
that case RSS offload is allowed.

Please check with configuration "port config 0 dcb vt off 4 pfc off".
