This patchset workarounds an PP2 HW limitation which prevents to use per-cpu rx buffers. The first patch is just a refactor to prepare for the second one. The second one allocates percpu buffers if the following conditions are met: - CPU number is less or equal 4 - no port is using jumbo frames
If the following conditions are not met at load time, of jumbo frame is enabled later on, the shared allocation is reverted.
