Previously, even if just one of the many fragments of a 9k packet
required a copy, we'd copy the whole packet into a freshly-allocated
9k-sized linear SKB, and this led to performance issues.
By having a pool of pages to copy into, each fragment can be
independently handled, leading to a reduced incidence of
allocation and copy.
