ec5f061564238892005257c83565a0b58ec79295 is the first bad commit commit ec5f061564238892005257c83565a0b58ec79295 Author: Pravin B Shelar <[email protected]> Date: Thu Mar 7 09:28:01 2013 +0000 net: Kill link between CSUM and SG features. Earlier SG was unset if CSUM was not available for given device to force skb copy to avoid sending inconsistent csum. Commit c9af6db4c11c (net: Fix possible wrong checksum generation) added explicit flag to force copy to fix this issue. Therefore there is no need to link SG and CSUM, following patch kills this link between there two features. This patch is also required following patch in series.
