uint16_t rx_buf_size

hardware receive buffer size.

Definition at line 1843 of file rte_ethdev.h.

uint8_t avail_thresh

Available Rx descriptors threshold defined as percentage of Rx queue size. If number of available descriptors is lower, the event RTE_ETH_EVENT_RX_AVAIL_THESH is generated. Value 0 means that the threshold monitoring is disabled.
