Hardware requires the number of rings in indirection table to be a power of 2. When setting number of channels to a non power of 2 number, indirection table is using only the closest power of 2 rings. Report this number in 'ethtool -x' and not the total number of rx rings. Signed-off-by:

clang flagged the following. All are actually cosmetic cleanups, not really bugs: drivers/net/ethernet/mellanox/mlx4/en_main.c:233:3: warning: Value stored to 'err' is never read err = -ENOMEM; ^ ~~~~~~~ drivers/net/ethernet/mellanox/mlx4/en_main.c:293:3: warning: Value stored to 'err' is never read err = -ENOMEM; drivers/net/ethernet/mellanox/mlx4/en_netdev.c:648:16: warning: Assigned value is garbage or undefined entry->reg_id = reg_id; ^ ~~~~~~ drivers/net/ethernet/mellanox/mlx4/en_netdev.c:659:2: warning: Function call argument is an uninitialized value mlx4_en_uc_steer_release(priv, priv->dev->dev_addr, *qpn, reg_id); (NOTE: reg_id is only used in the device-managed flow steering path, in which is it always initialized. This is not a bug. Cleanup here is therefore cosmetic only). drivers/net/ethernet/mellanox/mlx4/en_rx.c:122:3: warning: Value stored to 'frag_info' is never read frag_info = &priv->frag_info[i]; ^ ~~~~~~~~~~~~~~~~~~~ Signed-off-by:Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by:

The original motivation for this change was to allow the helper to be used in files other than actions.c as part of work on an odp select group action. It was as pointed out by Thomas Graf that this helper would be best off living in netlink.h. Furthermore, I think that the generic nature of this helper means it is best off in netlink.h regardless of if it is used more than one .c file or not. Thus, I would like it considered independent of the work on an odp select group action.

The internal and netdev vport remain part of openvswitch.ko. Encap vports including vxlan, gre, and geneve can be built as separate modules and are loaded on demand. Modules can be unloaded after use. Datapath ports keep a reference to the vport module during their lifetime. Allows to remove the error prone maintenance of the global list vport_ops_list.

This feature is defined in IEEE Std 802.11-2012, 10.23.13. It allows the AP devices to keep track of the hardware-address-to-IP-address mapping of the mobile devices within the WLAN network. The AP will learn this mapping via observing DHCP, ARP, and NS/NA frames. When a request for such information is made (i.e. ARP request, Neighbor Solicitation), the AP will respond on behalf of the associated mobile device. In the process of doing so, the AP will drop the multicast request frame that was intended to go out to the wireless medium. It was recommended at the LKS workshop to do this implementation in the bridge layer. vxlan.c is already doing something very similar. The DHCP snooping code will be added to the userspace application (hostapd) per the recommendation. This RFC commit is only for IPv4. A similar approach in the bridge layer will be taken for IPv6 as well. Signed-off-by:

This patch fixes trace formatting issues using the QETH_CARD_TEXT_ macro. The total size of each trace entry is 8 bytes. Some of the sprintf formats exceed these 8 bytes (for example using abcd:%d and the converted value needs more than 3 bytes). The solution is to shorten the text prepending the value or use a different format (%x). Signed-off-by:

A full Rx ring only requires 1 MiB of memory. This is not enough memory that it is useful to dynamically scale the number of Rx requests in the ring based on traffic rates, because: a) Even the full 1 MiB is a tiny fraction of a typically modern Linux VM (for example, the AWS micro instance still has 1 GiB of memory). b) Netfront would have used up to 1 MiB already even with moderate data rates (there was no adjustment of target based on memory pressure). c) Small VMs are going to typically have one VCPU and hence only one queue. Keeping the ring full of Rx requests handles bursty traffic better than trying to converge on an optimal number of requests to keep filled. On a 4 core host, an iperf -P 64 -t 60 run from dom0 to a 4 VCPU guest improved from 5.1 Gbit/s to 5.6 Gbit/s. Gains with more bursty traffic are expected to be higher. Signed-off-by:

Sowmini Varadhan says: ==================== sunvnet: NAPIfy sunvnet This patchset converts the sunvnet driver to use the NAPI framework. Changes since v4 to Patch1: vnet_event accumulates LDC_EVENT_* bits into rx_event. vnet_event_napi() unrolls send_events() logic to process all rx_event bits. Changes since v5: Patch 1: use net_device.h definition for NAPI_POLL_WEIGHT. Drop sparclinux changes (patch3) per David Miller feedback Patch 1 in the series addresses the packet-receive path- all the vnet_event() processing is moved into NAPI context. This patch is dependant on the sparc-next commit: "sparc64: Add vio_set_intr() to enable/disable Rx interrupts" (sparc commit id ca605b7d) Patch 2 uses RCU to fix race conditions between vnet_port_remove and paths that access/modify port-related state, such as vnet_start_xmit. Patch 3 leverages from the NAPIfied Rx path, dropping superfluous usage of the irqsave/irqrestores on the vio.lock where possible. ==================== Signed-off-by:

After the NAPIfication of sunvnet, we no longer need to synchronize by doing irqsave/restore on vio.lock in the I/O fastpath. NAPI ->poll() is non-reentrant, so all RX processing occurs strictly in a serialized environment. TX reclaim is done in NAPI context, so the netif_tx_lock can be used to serialize critical sections between Tx and Rx paths. Signed-off-by:
