under stress with traffic, which might result in application launch
failure.
+* **i40e: Enabled vector driver by default.**
+
+ Previously, vector driver is disabled by default as it cannot fill packet type
+ info for l3fwd to work well. Now there is an option for l3fwd to analysis
+ packet type softly, so enable vector driver by default.
+
* **mlx5: Fixed possible crash during initialization.**
A crash could occur when failing to allocate private device context.
other than IPv4 or IPv6, the mbuf was not released, and caused
a memory leak.
+* **l3fwd: Fixed using packet type blindly.**
+
+ l3fwd makes use of packet type information without even query if devices or PMDs
+ really set it. For those don't set ptypes, add an option to parse it softly.

* **examples/vhost: Fixed frequent mbuf allocation failure.**
vhost-switch often fails to allocate mbuf when dequeue from vring because it
