What are these fields what do they do? https://doc.dpdk.org/api/structrte__eth__thresh.html uint8_t pthresh uint8_t hthresh uint8_t wthresh And here: What is the RS bit? https://doc.dpdk.org/api/structrte__eth__txconf.html uint16_t tx_rs_thresh. And some what unrelated: What is a ``doorbell"? this is something I continue to run into esp. in Mellanox NIC papers? Doorbell counts are reported for AWS NICs at least with xstats api: tx_q0_doorbells: 18812 tx_q1_doorbells: 18861 [-- Attachment #2: Type: text/html, Size: 1364 bytes --]
