[NET] gso: Fix up GSO packets with broken checksums
Certain subsystems in the stack (e.g., netfilter) can break the partial checksum on GSO packets. Until they're fixed, this patch allows this to work by recomputing the partial checksums through the GSO mechanism. Once they've all been converted to update the partial checksum instead of clearing it, this workaround can be removed. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
