Hi,
we are proud to announce ENAv2 driver for the DPDK.
It is already available for the Linux, and now also ENAv2 can be used with
DPDK on the appropriate AWS instances.
To summarize, this release contains:
**New major features**
* LLQv2 which is Low Latency Queue v2. This feature reduces the latency
of the packets by pushing the header directly through the PCI to the
device, before the DMA is even triggered. This allows the NIC to
asynchronously prepare for the next incoming packet, when the DMA will
be finished.
* Independent configuration of HW Tx and Rx ring depths. Also, on some
instances it is possible to create 8k Rx descriptors per ring.
* Additional doorbell check on Tx, to handle Tx more efficiently for big
bursts of packets
* Per queue statistics
* Extended statistics using xstats DPDK API
**New major bug fixes**
* The reset routine was aligned with the DPDK API, so now it can be
handled as in other PMDs
* Fixes for OOO completion
* Fixes for memory leaks due to port stops and starts in the middle of
traffic
There are also minor bug fixes and features in addition to the ones
mentioned above.
