Detailed Description

struct efx_rx_queue - An Efx RX queue : The associated Efx NIC : Index of network core RX queue. Will be >= 0 iff this is associated with a real RX queue. : The software buffer ring : The hardware descriptor ring : The size of the ring minus 1. : Receive queue enabled indicator. : Set when a RX flush is pending. Has the same lifetime as . : Number of buffers added to the receive queue. : Number of buffers given to NIC (<= ). : Number of buffers removed from the receive queue. : RX descriptor maximum fill level (<= ring size) : RX descriptor fill level that will trigger a fast fill (<= ) : RX descriptor minimum non-zero fill level. This records the minimum fill level observed when a ring refill was triggered. : RX allocation strategy counter. : RX allocation strategy counter. : Timer used to defer efx_nic_generate_fill_event().
