The temporary copy of the VLAN group is not neccessary since the lower device is already in the process of being unregistered, if it was neccessary the memset of the global group would introduce a race condition. With this removed, the changes to the original code are only a few lines, so remove the new function and move the code back into vlan_device_event(). Signed-off-by:

When GRO is successfully merging received packets, we should allocate raw page buffers rather than skbs that will be discarded by GRO. Otherwise, we should allocate skbs. GRO also benefits from higher interrupt moderation, so increase the score for mergeable RX packets. Signed-off-by:

Ben Hutchings authored
This will allow drivers to adjust their receive path dynamically based on whether GRO is being applied successfully. Currently all in-tree callers ignore the return values of these functions and do not need to be changed. Signed-off-by:

Currently PACKET_TX_RING forces certain amount of every frame to remain unused. This probably originates from an early version of the PACKET_TX_RING patch that in fact used the extra space when the (since removed) CONFIG_PACKET_MMAP_ZERO_COPY option was enabled. The current code does not make any use of this extra space. This patch removes the extra space reservation and lets userspace make use of the full frame size. Signed-off-by:

proto_ops->getname implies copying protocol specific data into storage unit (particulary to __kernel_sockaddr_storage). So when we implement new protocol support we should keep such a detail in mind (which is easy to forget about). Lets introduce DECLARE_SOCKADDR helper which check if storage unit is not overfowed at build time. Eventually inet_getname is switched to use DECLARE_SOCKADDR (to show example of usage).

Some workloads hit dev_base_lock rwlock pretty hard. We can use RCU lookups to avoid touching this rwlock. netdevices are already freed after a RCU grace period, so this patch adds no penalty at device dismantle time. dev_ifname() converted to dev_get_by_index_rcu() Signed-off-by:

The CAPI interface incorrectly assumed that CAPI messages would always start at the beginning of the data buffer: fix by treating DATA_B3 messages as the link layer header to their payload data. This fix changes the way acknowledgement information is propagated through the hardware specific modules and thereby impacts the ISDN4Linux variant of the driver, too. Also some assumptions about methods not being called from interrupt context turned out to be unwarranted; fix by using dev_kfree_skb_any() wherever non-interrupt context isn't guaranteed.

I found that the current version of drivers/net/usb/dm9601.c can be used to successfully drive a low-power, low-cost network adapter with USB ID 0a46:9000, based on a DM9000E chipset. As no device with this ID is yet present in the kernel, I have created a patch that adds support for the device to the dm9601 driver. Created and tested against linux-2.6.32-rc5. Signed-off-by:
