Refactor some code in the RX path to allow prefetching some data from the
packet header. The first patch is only a refactor, the second one
reduces the data synced, while the third one adds the prefetch.

The packet rate improvement with the second patch is very small (1606 => 1620 kpps),
while the prefetch bumps it up by 14%: 1620 => 1853 kpps.

Matteo Croce (3):
  mvpp2: refactor frame drop routine
  mvpp2: sync only by the frame size
  mvpp2: prefetch frame header
