Subject: i40e: How the packets will be processed when status_error_len is 0

Hi all,

	If the packets arrive at the rx and then raise soft irq to handle it, but in i40e_clean_rx_irq, status_error_len is 0 and return.
	The data isn't fetchted from the rx buffer, so the how the packets arrive at the rx will be processed?

	FYI, the every rx/tx queue has been bounded to one cpu(64 queues, 64 cpus).

Thanks!
