Introduce __ipv6_addr_diff64() to to find the first different bit between two addresses on 64bit architectures. 32bit version is still available as __ipv6_addr_diff32(), and __ipv6_addr_diff() automatically selects appropriate version. Signed-off-by:

Commit 7a3198a8 ("ipv6: helper function to get tclass") introduced ipv6_tclass(), but similar function is already available as ipv6_get_dsfield(). We might be able to call ipv6_tclass() from ipv6_get_dsfield(), but it is confusing to have two versions. Signed-off-by:

This is not only for readability but also for optimization. What we do here is to build the 32bit word at the beginning of the ipv6 header (the "ip6_flow" virtual member of struct ip6_hdr in RFC3542) and we do not need to read the tclass portion of the target buffer. Signed-off-by:

When the Bridge Loop Avoidance component is not compiled-in, its boolean switch should be not compiled as well. This patch surrounds the switch with a proper ifdef.

Different hashes have the same class key because they get initialised with the same one. For this reason lockdep can create false warning when they are used recursively. Re-initialise the key for each hash after the invocation to hash_new() to avoid this problem. Signed-off-by:

The flag field of the tt_local_entry->common structure in tt_local_add() is first assigned NO_FLAGS and then TT_CLIENT_NEW so nullifying the first operation. For this reason it is safe to remove the first assignment. This was introuduced by ("batman-adv: keep local table consistency for further TT_RESPONSE") Signed-off-by: -

Values are printed in hexadecimal format in several points in the code, but they are not printed using the same format string. This patches unifies the format used for such numbers so that they look the same everywhere. Given the fact that all the variables printed as hexadecimal are 16 bit long, this is the chosen printing format: %#.4x Signed-off-by:

The current timeout is set to one hour. However a client connected to the mesh network will always generate traffic. In the worst case it will send ARP requests every 4 or 5 minutes. On the other hand having a long timeout means storing dead entries for one hour and it leads to very big trans-tables containing useless clients. This patch reduces the timeout to 10 minutes Signed-off-by:

The current translation table mechanism is not suitable for multicast addresses and we are currently flooding such frames anyway. Therefore this patch prevents multicast MAC addresses being added to the translation table. Signed-off-by:

Output of a git grep happened to make me look into this file, and I found instructions about how to hand patch (without using patch) the driver into the kernel tree. Since the driver has been a part of the mainline kernel for years, we can dump this whole section. Fortunately it doesn't even cause a renumbering of the sections to do so. Signed-off-by:

When testing with FCoE enabled we discovered that I had not exported __netdev_pick_tx. As a result ixgbe doesn't build with the RFC patches applied because ixgbe_select_queue was calling the function. This change corrects that build issue by correctly exporting __netdev_pick_tx so it can be used by modules. Signed-off-by:

This patch makes it so that we can support transmit packet steering without sysfs needing to be enabled. The reason for making this change is to make it so that a driver can make use of the XPS even while the sysfs portion of the interface is not present. Signed-off-by:

This change is meant to address several issues I found within the netif_set_xps_queues function. If the allocation of one of the maps to be assigned to new_dev_maps failed we could end up with the device map in an inconsistent state since we had already worked through a number of CPUs and removed or added the queue. To address that I split the process into several steps. The first of which is just the allocation of updated maps for CPUs that will need larger maps to store the queue. By doing this we can fail gracefully without actually altering the contents of the current device map. The second issue I found was the fact that we were always allocating a new device map even if we were not adding any queues. I have updated the code so that we only allocate a new device map if we are adding queues, otherwise if we are not adding any queues to CPUs we just skip to the removal process. The last change I made was to reuse the code from remove_xps_queue to remove the queue from the CPU. By making this change we can be consistent in how we go about adding and removing the queues from the CPUs. Signed-off-by:

This patch does a minor refactor on netif_reset_xps_queue to address a few items I noticed. First is the fact that we are doing removal of queues in both netif_reset_xps_queue and netif_set_xps_queue. Since there is no need to have the code in two places I am pushing it out into a separate function and will come back in another patch and reuse the code in netif_set_xps_queue. The second item this change addresses is the fact that the Tx queues were not getting their numa_node value cleared as a part of the XPS queue reset. This patch resolves that by resetting the numa_node value if the dev_maps value is set. Signed-off-by:

This patch adds two functions, netif_reset_xps_queue and netif_set_xps_queue. The main idea behind these two functions is to provide a mechanism through which drivers can update their defaults in regards to XPS. Currently no such mechanism exists and as a result we cannot use XPS for things such as ATR which would require a basic configuration to start in which the Tx queues are mapped to CPUs via a 1:1 mapping. With this change I am making it possible for drivers such as ixgbe to be able to use the XPS feature by controlling the default configuration. Signed-off-by:

This change splits the core bits of netdev_pick_tx into a separate function. The main idea behind this is to make this code accessible to select queue functions when they decide to process the standard path instead of their own custom path in their select queue routine. Signed-off-by:
