Hi，
I have update the code into 20.05-rc2. However， the l3fwd-power

I am using 20.05-rc2 version to test based on HNS3 NIC
hardware, and
found that after starting l3fwd-power,
using ctrl+c cannot force quit. But I revert the patch(33666b4 service:
fix crash on exit) and it is ok.
We had a fix in rc1 that is supposed to fix this.

Hi, David Marchand
I am only merged the patch(examples/l3fwd-power: implement proper
shutdown) based on 20.05-rc0 and test. the bug is not resolved.
Can you provide me with complete solution? I want to understand the
cause of the whole problem
Hi Lijun,
The complete solution is to use a version with all of the fixes, as
Anatoly suggested previously. I have just checked out the latest tip of
the master branch, and l3fwd-power exits gracefully with a single CTRL-C:
...
