gro: New frags interface to avoid copying shinfo
It turns out that copying a 16-byte area at ~800k times a second can be really expensive :) This patch redesigns the frags GRO interface to avoid copying that area twice. The two disciples of the frags interface have been converted. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
