This cleans up error handling for the beacon in case of dma mapping failure. We need to free the skb when dma mapping fails instead of nulling and leaking the pointer, and we should bail out to avoid giving the hardware the bad descriptor. Finally, we need to perform the null check after trying to update the beacon, or else beacons will never be sent after a single mapping failure.

2011-08-01rtlwifi: Fix kernel oops on ARM SOCLarry Finger1-9/+11
This driver uses information from the self member of the pci_bus struct to get information regarding the bridge to which the PCIe device is attached. Unfortunately, this member is not established on all architectures, which leads to a kernel oops. Skipping the entire block that uses the self member to determine the bridge vendor will only affect RTL8192DE devices as that driver sets the ASPM support flag differently when the bridge vendor is Intel. If the self member is available, there is no functional change. This patch fixes Bugzilla No. 40212.

The main point of my patch was to change the output and I would like to get that included. Here is my updated patch... Subject: [PATCH net-next-2.6 v2] bonding: reduce noise during init Many are using sysfs to configure bonding rather than module options, so there is no need for bonding to throw this warning in normal cases. Keep the message around when debugging is enabled as it might be useful for someone desperate enough to enable debugging, but eliminate it otherwise.

2011-07-27bonding: fix string comparison errorsAndy Gospodarek1-62/+71
When a bond contains a device where one name is the subset of another (eth1 and eth10, for example), one cannot properly set the primary device or the currently active device. This was reported and based on work by Takuma Umeya. I also verified the problem and tested that this fix resolves it. V2: A few did not like the the current code or my changes, so I refactored bonding_store_primary and bonding_store_active_slave to be a bit cleaner, dropped the use of strnicmp since we did not really need the comparison to be case insensitive, and formatted the input string from sysfs so a comparison to IFNAMSIZ could be used. I also discovered an error in bonding_store_active_slave that would modify bond->primary_slave rather than bond->curr_active_slave before forcing the bonding driver to choose a new active slave. V3: Actually sending the proper patch.... Signed-off-by: Andy Gospodarek <andy@greyhouse.net> Reported-by: Takuma Umeya <tumeya@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-07-27net: Audit drivers to identify those needing IFF_TX_SKB_SHARING clearedNeil Horman8-6/+14
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.

For some reason, when rxaccel is disabled, NV_RX3_VLAN_TAG_PRESENT is still set and some pseudorandom vids appear. So check for NETIF_F_HW_VLAN_RX as well.
