I am wondering if there is a race condition between the flow-mod and the
incoming packet.

When ovs userspace receives a flow-mod message from a remote controller,
does it has higher priority over processing incoming packets (kernel
upcalls) or this flow-mod message and the flow miss upcalls are processed
concurrently?

Best,
Xiaoye
