Identical code, we just need to call a layer-specific hook to process any received buffer. qeth_buffer_reclaim_work() is shuffled around to avoid a forward declaration for qeth_queue_input_buffer(). Signed-off-by:

There's no need to have struct bpf_map_type_list since it just contains a list_head, the type, and the ops pointer. Since the types are densely packed and not actually dynamically registered, it's much easier and smaller to have an array of type->ops pointer. Also initialize this array statically to remove code needed to initialize it. In order to save duplicating the list, move it to the types header file added by the previous patch and include it in the same fashion. Signed-off-by:

There's no point in checking for duplicate sessions at the beginning of l2tp_nl_cmd_session_create(); the ->session_create() callbacks already return -EEXIST when the session already exists. Furthermore, even if l2tp_session_find() returns NULL, a new session might be created right after the test. So relying on ->session_create() to avoid duplicate session is the only sane behaviour.

Benjamin Herrenschmidt says: ==================== ftgmac100: Rework batch 3 - TX path This is version 2 of the third batch of updates to the ftgmac100 driver. This one tackles the TX path of the driver. This provides the bulk of the performance improvements by adding support for fragmented sends along with a bunch of cleanups. Version 2 fixes a patch splitting mistake and uses eth_skb_pad() (which uses skb_put_padto) to pad ethernet frames rather than skb_padto(), thus removing the need to also pad the packet headlen in a couple of places. Subsequent batches will add various features (ethtool functions, vlan offlan, ...) and cleanups. ==================== Signed-off-by: -

We'll use variants of this accessor without barriers when building series of descriptors for fragmented sends Signed-off-by:
-
Benjamin Herrenschmidt authored
We have a private lock which isn't terribly useful, and we maintain a "tx_pending" counter for information that's already available via a trivial arithmetic operation. Then we unconditionaly wake the queue even when not stopped. Finally our code in tx isn't really safe vs. a concurrent reclaim. The aspeed chips aren't SMP today but I prefer the code being right and future proof. So rip that out and replace it with more "standard" queue handling, currently with a threshold of 1 queue element, which will be increased when we implement fragmented sends. Signed-off-by:

Benjamin Herrenschmidt authored
Rather than in the descriptor. The descriptor is mapped non-cachable and rather slow to access. Since to do that we need to keep track of the tx "pointer" we also have no use of all the accesors to manipulate it, just open code it, it's as clear and will help when adding fragmented sends.

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-04-08 This series contains updates to i40e and i40evf only. Mitch fixes an issue where the client driver (i40iw) was attempting to load on x710 devices (which do not support iWARP), so only register with the client if iWARP is supported. Jake fixes up error messages to better clarify to the user when adding a invalid flow type. Updates the driver to look up the MAC address from eth_get_platform_mac_address() first before checking what the firmware provides. Cleans up code so we are not repeating a duplicate loop, by checking both transmit and receive queues in a single loop. Also cleans up flags never used, so remove the definitions. Alex does cleanup so that we are always updating pf->flags when a change is made to the private flags. Adds support for 3K buffers to the receive path so that we can provide the additional padding needed in the event of NET_IP_ALIGN being non-zero or a cache line being greater than 64. Adds support for build_skb() to i40e/i40evf. Maciej adjusts the scope of the rtnl lock held during reset because it was stopping other PFs from running their reset procedures. Alan reduces code complexity in i40e_detect_recover_hung_queue(). ==================== Signed-off-by:
