This patch uses pskb_expand_head to expand the existing skb and linearize

Seems sane to me.


it if needed.  Actually, someone should sift through every instance of
skb_pad on a non-linear skb as they do not fit the reasons why this was
originally created.

Non-linear skbs smaller than ETH_ZLEN seem unlikely.

Overall, the skb_pad() changes were made over a short span of time, often to older and under-used drivers, so I would not be surprised to find rough edges or the occasional bug.
