From 550fd08c2cebad61c548def135f67aba284c6162 Mon Sep 17 00:00:00 2001 From: Neil Horman <nhorman@tuxdriver.com> Date: Tue, 26 Jul 2011 06:05:38 +0000 Subject: net: Audit drivers to identify those needing IFF_TX_SKB_SHARING cleared After the last patch, We are left in a state in which only drivers calling ether_setup have IFF_TX_SKB_SHARING set (we assume that drivers touching real hardware call ether_setup for their net_devices and don't hold any state in their skbs. There are a handful of drivers that violate this assumption of course, and need to be fixed up. This patch identifies those drivers, and marks them as not being able to support the safe transmission of skbs by clearning the IFF_TX_SKB_SHARING flag in priv_flags Signed-off-by: Neil Horman <nhorman@tuxdriver.com> CC: Karsten Keil <isdn@linux-pingi.de> CC: "David S.
