Hello,
In userspace dpdk OVS, as I understand, each PMD thread can poll packets
from multiple dpdk ports the thread owns.
Then, what about transmit?
Suppose 2 PMD threads are running, if route lookup in 1st PMD thread
results in a dpdk port (as outgoing port) which 2nd PMD thread owns,
then how does the 1st PMD thread sends the packet over the port the 2nd PMD
thread owns?
>From concurrency perspective, can he 1st PMD thread safely call transmit
API with the port owned by 2nd PMD thread owns?
