  Since 20.05, l3fwd-power has become much more stringent about
whether it allows initialization without initializing the
librte_power library with it. This means that while previously
the app could have been used to test RX interrupts functionality
even if the app itself was in a half-working state, it is now
no longer possible to do so.

To address this use case, we're adding an interrupt-only mode
that does not rely on librte_power or telemetry. This enables
using l3fwd-power in environments where librte_power is not
expected to work (such as inside a VM or on non-IA
architectures). The RX/TX path is basically copy paste from
legacy RX/TX path but with librte_power bits taken out.

There seem to be two opposing schools of thought on whether we
should have more or less examples. This patchset goes in the
"less" direction where we add a new mode to an existing app,
rather than creating a new one like it could be argued it
deserves.

Anatoly Burakov (3):
  l3fwd-power: disable interrupts by default
  l3fwd-power: only allow supported power library envs
  l3fwd-power: add interrupt-only mode
