This patch set changes the behaviour in case the Tx path is confroted
with an SKB with insufficient headroom for our hardware necessities (SW
annotation area). In the first patch, instead of realloc-ing the SKB we
now send a S/G frames descriptor while the second one adds a new
software held counter to account for for these types of frames.

  dpaa2-eth: add software counter for Tx frames converted to S/G
