process_responses - process responses from an SGE response queue : the ingress response queue to process : how many responses can be processed in this round
Process responses from a Scatter Gather Engine response queue up to the supplied budget. Responses include received packets as well as control messages from firmware or hardware.
Additionally choose the interrupt holdoff time for the next interrupt on this queue. If the system is under memory shortage use a fairly long delay to help recovery.

t4vf_sge_alloc_rxq - allocate an SGE RX Queue : the adapter : pointer to to the new rxq's Response Queue to be filled in : if 0, a normal rspq; if 1, an asynchronous event queue : the network device associated with the new rspq : MSI-X vector index (overriden in MSI mode) : pointer to the new rxq's Free List to be filled in : the interrupt handler to invoke for the rspq
t4vf_sge_init - initialize SGE : the adapter
Performs SGE initialization needed every time after a chip reset. We do not initialize any of the queue sets here, instead the driver top-level must request those individually. We also do not enable DMA here, that should be done after the queues have been set up.
