The definition of static_key_slow_inc() has cpus_read_lock in place. In the virtio_net driver, XPS queues are initialized after setting the queue:cpu affinity in virtnet_set_affinity() which is already protected within cpus_read_lock. Lockdep prints a warning when we are trying to acquire cpus_read_lock when it is already held. This patch adds an ability to call __netif_set_xps_queue under cpus_read_lock(). Acked-by:

The totally undocumented IO mode needs to be set to enumerator 0 to enable port 4 also known as WAN in most configurations, for ordinary traffic. The 3 bits in the register come up as 010 after reset, but need to be set to 000. The Realtek source code contains a name for these bits, but no explanation of what the 8 different IO modes may be. Set it to zero for the time being and drop a comment so people know what is going on if they run into trouble. This "mode zero" works fine with the D-Link DIR-685 with RTL8366RB. Signed-off-by:

IPv6 GRO over GRE tap is not working while GRO is not set over the native interface. gro_list_prepare function updates the same_flow variable of existing sessions to 1 if their mac headers match the one of the incoming packet. same_flow is used to filter out non-matching sessions and keep potential ones for aggregation. The number of bytes to compare should be the number of bytes in the mac headers. In gro_list_prepare this number is set to be skb->dev->hard_header_len. For GRE interfaces this hard_header_len should be as it is set in the initialization process (when GRE is created), it should not be overridden. But currently it is being overridden by the value that is actually supposed to represent the needed_headroom. Therefore, the number of bytes compared in order to decide whether the the mac headers are the same is greater than the length of the headers. As it's documented in netdevice.h, hard_header_len is the maximum hardware header length, and needed_headroom is the extra headroom the hardware may need. hard_header_len is basically all the bytes received by the physical till layer 3 header of the packet received by the interface. For example, if the interface is a GRE tap then the needed_headroom should be the total length of the following headers: IP header of the physical, GRE header, mac header of GRE. It is often used to calculate the MTU of the created interface. This patch removes the override of the hard_header_len, and assigns the calculated value to needed_headroom. This way, the comparison in gro_list_prepare is really of the mac headers, and if the packets have the same mac headers the same_flow will be set to 1. Performance testing: 45% higher bandwidth.

Manish Chopra says: ==================== qed*: Enhancements This patch series adds following support in drivers - 1. Egress mqprio offload. 2. Add destination IP based flow profile. 3. Ingress flower offload (for drop action). Please consider applying this series to "net-next". ==================== Signed-off-by: -
Manish Chopra authored
The main motive of this patch is to lay down driver's tc offload infrastructure in place. With these changes tc can offload various supported flow profiles (4 tuples, src-ip, dst-ip, l4 port) for the drop action. Dropped flows statistic is a global counter for all the offloaded flows for drop action and is populated in ethtool statistics as common "gft_filter_drop". Examples - tc qdisc add dev p4p1 ingress tc filter add dev p4p1 protocol ipv4 parent ffff: flower \ skip_sw ip_proto tcp dst_ip 192.168.40.200 action drop tc filter add dev p4p1 protocol ipv4 parent ffff: flower \ skip_sw ip_proto udp src_ip 192.168.40.100 action drop tc filter add dev p4p1 protocol ipv4 parent ffff: flower \ skip_sw ip_proto tcp src_ip 192.168.40.100 dst_ip 192.168.40.200 \ src_port 453 dst_port 876 action drop tc filter add dev p4p1 protocol ipv4 parent ffff: flower \ skip_sw ip_proto tcp dst_port 98 action drop Signed-off-by:

This patch adds support for dropping and redirecting the flows based on destination IP in the packet. This also moves the profile mode settings in their own functions which can be used through tc flows in successive patch. For example - ethtool -N p5p1 flow-type tcp4 dst-ip 192.168.40.100 action -1 ethtool -N p5p1 flow-type udp4 dst-ip 192.168.50.100 action 1 ethtool -N p5p1 flow-type tcp4 dst-ip 192.168.60.100 action 0x100000000 Signed-off-by:

This patch adds support for tc mqprio offload, using this different traffic classes on the adapter can be utilized based on configured priority to tc map. For example - tc qdisc add dev eth0 root mqprio num_tc 4 map 0 1 2 3 This will cause SKBs with priority 0,1,2,3 to transmit over tc 0,1,2,3 hardware queues respectively. Signed-off-by:

Allocating the main qeth_card struct with GFP_DMA blocks us from moving it into netdev_priv(). But the only reason why we need DMA memory is the ccw1 structs embedded into each ccw channel. So extract those into separate allocations, like we already do for the cmd buffers. Signed-off-by:

The data channel currently doesn't need a setup operation, because we don't use pre-allocated cmd buffers for its IO. But subsequent changes will introduce further setup that also applies to the data channel. This refactors things a bit, so that the new stuff can then be automatically applied to all channels.

Jose Abreu says: ==================== Add support for XGMAC2 in stmmac This series adds support for 10Gigabit IP in stmmac. The IP is called XGMAC2 and has many similarities with GMAC4. Due to this, its relatively easy to incorporate this new IP into stmmac driver by adding a new block and filling the necessary callbacks. The functionality added by this series is still reduced but its only a starting point which will later be expanded. I splitted the patches into funcionality and to ease the review. Only the patch 8/9 really enables the XGMAC2 block by adding a new compatible string. Version 4 addresses review comments of Florian Fainelli and Rob Herring. NOTE: Although the IP supports 10G, for now it was only possible to test it at 1G speed due to 10G PHY HW shipping problems.

Andrew Lunn says: ==================== More complete PHYLINK support for mv88e6xxx Previous patches added sufficient PHYLINK support to the mv88e6xxx that it did not break existing use cases, basically fixed-link phys. This patchset builds out the support so that SFP modules, up to 2.5Gbps can be supported, on mv88e6390X, on ports 9 and 10. It also provides a framework which can be extended to support SFPs on ports 2-8 of mv88e6390X, 10Gbps PHYs, and SFP support on the 6352 family. Russell King did much of the initial work, implementing the validate and mac_link_state calls. However, there is an important TODO in the commit message: needs to call phylink_mac_change() when the port link comes up/goes down. The remaining patches implement this, by adding more support for the SERDES interfaces, in particular, interrupt support so we get notified when the SERDES gains/looses sync. This has been tested on the ZII devel C, using a Clearfog as peer device. ==================== Signed-off-by: -

phylink wants to know when the MAC layers notices a change in the link. For the 6390 family, this is a change in the SERDES state. Add interrupt support for the SERDES interface used to implement SGMII/1000Base-X/2500Base-X. This is currently limited to ports 9 and 10. Support for the 10G SERDES and other ports will be added later, building on this basic framework. Signed-off-by:
