I think the LC PPMd is needed even for inline, because the LU can't
communicate with RE about what is needed to be done, so the LC PPMd
still handles the communication between RE, RE asks it do PPM for
something, then it may further delegate to NPU. So in your example,
the BFD are all further offloaded to NPU, LACP is not.
