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.
