Update sge initialization with respect to free-list manager configuration and ingress arbiter. Also update refill logic to refill mbufs only after a certain threshold for rx. Optimize tx packet prefetch. Approx. 3 MPPS improvement seen in forwarding performance after the optimization.

Resolved Issues
|
|
---------------
|
|
|
|
EAL
|
|
~~~
|
|
|
|
* **eal/linux: Fixed epoll timeout.**
|
|
|
|
Fixed issue where the ``rte_epoll_wait()`` function didn't return when the
|
|
underlying call to ``epoll_wait()`` timed out.
|
|
|
|
|
|
Drivers
|
|
~~~~~~~
|
|
|
|
* **ixgbe: Fixed issue with X550 DCB.**
|
|
|
|
Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet
|
|
with user priority 6 or 7 was injected to the NIC, then the NIC would only
|
|
put 3 packets into the queue. There was also a similar issue for 4 TCs.
|
|
|
|
* **ixgbe: Removed burst size restriction of vector RX.**
|
|
|
|
Fixed issue where a burst size less than 32 didn't receive anything.
|
|
|
|
* **i40e: Fixed base driver allocation when not using first numa node.**
|
|
|
|
Fixed i40e issue that occurred when a DPDK application didn't initialize
|
|
ports if memory wasn't available on socket 0.
|
|
|
|
* **vhost: Fixed Qemu shutdown.**
|
|
|
|
Fixed issue with libvirt ``virsh destroy`` not killing the VM.
|
|
|
|
|
|
Libraries
|
|
~~~~~~~~~
|
|
|
|
* **hash: Fixed memory allocation of Cuckoo Hash key table.**
|
|
|
|
Fixed issue where an incorrect Cuckoo Hash key table size could be
|
|
calculated limiting the size to 4GB.
