This feature reduces the latency + of the packets by pushing the header directly through the PCI to the + device. This allows the NIC to start handle packet right after the doorbell + without waiting for DMA. + * Added independent configuration of HW Tx and Rx ring depths. + * Added support for up to 8k Rx descriptors per ring. + * Added additional doorbell check on Tx, to handle Tx more efficiently for big + bursts of packets. + * Added per queue statistics. + * Added extended statistics using xstats DPDK API. + * The reset routine was aligned with the DPDK API, so now it can be + handled as in other PMDs. + * Fixed out of order (OOO) completion. + * Fixed memory leaks due to port stops and starts in the middle of + traffic. + * Updated documentation and features list of the PMD. + * **Updated the enic driver.** * Added support for ``RTE_ETH_DEV_CLOSE_REMOVE`` flag. -- 2.20.1
