Michael,
Would you please give an example or two how these two flags DESC_DRIVER and DESC_WRAP are used together? Like others, I am confused by the description and still don?t quite grok it.

kernel vhost demands an interrupt from guest when the ring is full in order to enable guest to submit new packets to the queue
Folks,
We came across a memory race condition between VPP vhost driver and the kernel vhost. VPP is running a tap interface over vhost backend. In this case, VPP is acting as the vhost driver mode and the kernel vhost is acting as the vhost device mode.
In the kernel vhost?s TX traffic direction which is VPP?s RX traffic direction, kernel vhost is the producer and VPP is the consumer. Kernel
