3.16.7-ckt11 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Tom Herbert <[email protected]> commit 4e18b9adf2f910ec4d30b811a74a5b626e6c6125 upstream. This function changes ip_summed to CHECKSUM_NONE if CHECKSUM_COMPLETE is set. This is called to discard checksum-complete when packet is being modified and checksum is not pulled for headers in a layer. Signed-off-by: Tom Herbert <[email protected]> Signed-off-by: David S.
