Iyappan Subramanian says: ==================== Add support for Classifier and RSS This patch set enables, (i) Classifier engine that is used for parsing through the packet and extracting a search string that is then used to search a database to find associative data. (ii) Receive Side Scaling (RSS) that does dynamic load balancing of the CPUs by controlling the number of messages enqueued per CPU though the help of Toeplitz Hash function of 4-tuple of source TCP/UDP port, destination TCP/UDP port, source IPV4 address and destination IPV4 address. (iii) Multi queue, to make advantage of RSS v3: Address review comments from v2 - reordered local variables from longest to shortlest line v2: Address review comments from v1 - fix kbuild warning - add default coalescing v1: - Initial version ==================== Signed-off-by:Iyappan Subramanian <isubramanian@apm.com> Signed-off-by:

By packing the structure we can remove a few holes as Jamal suggests. before: struct tc_cls_u32_knode { struct tcf_exts * exts; /* 0 8 */ u8 fshift; /* 8 1 */ /* XXX 3 bytes hole, try to pack */ u32 handle; /* 12 4 */ u32 val; /* 16 4 */ u32 mask; /* 20 4 */ u32 link_handle; /* 24 4 */ /* XXX 4 bytes hole, try to pack */ struct tc_u32_sel * sel; /* 32 8 */ /* size: 40, cachelines: 1, members: 7 */ /* sum members: 33, holes: 2, sum holes: 7 */ /* last cacheline: 40 bytes */ }; after: struct tc_cls_u32_knode { struct tcf_exts * exts; /* 0 8 */ struct tc_u32_sel * sel; /* 8 8 */ u32 handle; /* 16 4 */ u32 val; /* 20 4 */ u32 mask; /* 24 4 */ u32 link_handle; /* 28 4 */ u8 fshift; /* 32 1 */ /* size: 40, cachelines: 1, members: 7 */ /* padding: 7 */ /* last cacheline: 40 bytes */ }; Suggested-by:Jamal Hadi Salim <jhs@mojatatu.com> Signed-off-by:

The timeout is a long, we return it truncated if it is huge. Basically harmless as the only caller does a boolean check, but tidy it up anyway. (64bit build tested this time. Thank you 0day) Signed-off-by:

This patch moves the qed* driver into utilizing the 8.7.3.0 FW. This new FW is required for a lot of new SW features, including: - Vlan filtering offload - Encapsulation offload support - HW ingress aggregations As well as paving the way for the possibility of adding storage protocols in the future. V2: - Fix kbuild test robot error/warnings. Signed-off-by:

Since commit 8b570dc9 ("sctp: only drop the reference on the datamsg after sending a msg") used sctp_datamsg_put in sctp_sendmsg, instead of sctp_datamsg_free, this function has no use in sctp. So we will remove it. Signed-off-by:

__sctp_lookup_association() is only invoked by sctp_v4_err() and sctp_rcv(), both which run on the rx BH, and it has been protected by rcu_read_lock [see ip_local_deliver_finish() / ipv6_rcv()]. So we can move it to sctp_lookup_association, only let sctp_lookup_association use rcu_read_lock. Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-02-17 This series contains updates to i40e/i40evf only. Jesse cleans up a duplicate declaration in probe. Then fixes a bug where the driver was using a offset based off a DMA handle while mapping and unmapping using sync_single_range_for_[cpu|device], when it should be using DMA handle (returned from alloc_coherent) and the offset of the memory to be sync'd. Fixed an issue where sync_vsi_filter() was allocating memory in a way that could sleep (GFP_KERNEL) which was causing a problem when called by the team driver under rcu_read_lock(). Shannon adds a check to ensure we do not attempt to do TSO when skb->ip_summed is not set to CHECKSUM_PARTIAL. Kiran add functions related to port mirroring features such as add/delete mirror rule. Jacob assigns the i40e_pf structure directly instead of using a large memcpy, to avoid a sparse warning and lets the compiler optimize the copy since it know the size of the structure in advance. Anjali enables GENEVE capability for XL710/X710 devices with firmware API version higher than 1.4. Added flag for automatic rule eviction feature for X722, which is disabled by default. ==================== Signed-off-by: -

Tom Lendacky says: ==================== amd-xgbe: AMD XGBE driver updates 2016-02-12 The following updates and fixes are included in this driver update series: - Disable VLAN filtering in promiscuous mode - Change from using napi_complete to napi_complete_done - Use __napi_schedule_irqoff when running in interrupt context - Verify ethtool speed setting is valid for the selected speedset - Enable PFC based on the pfc_en setting - Fix the mapping of priorities to traffic classes - Do traffic class setup when DCB nl callbacks are invoked - Check Rx queue fifos before stopping Rx queue DMA - Switch from disable_irq to masking interrupts for auto-negotiation This patch series is based on net-next. Changes from v1: - Removed #ifndef and #define of CRCPOLY_LE as part of the patch to disable VLAN filtering in promiscuous mode - Reworked changes to xgbe_setup_tc to resolve conflicts with commit 16e5cc64 (net: rework setup_tc ndo op to consume general tc operand) ==================== Signed-off-by:

Lendacky, Thomas authored
Currently the auto-negotiation interrupt handling disables the irq instead of masking off the interrupts. This was done because the phy library was originally used to read and write the PCS registers, which could not be performed in interrupt context. Now that the phy library is no longer used to read and write the PCS registers the interrupts can be masked off in the interrupt service routine eliminating the need to call disable_irq/enable_irq. This also requires changing the protection mutex to a spinlock. Signed-off-by:

Currently the netdev traffic class setup is only performed when invoked through the ndo_setup_tc interface. However, the same setup should be performed when the dcbnl interface (ieee_setets) is invoked. Rework the netdev traffic class setup to be invokable through either interface and also provide the priority to traffic class mapping if available. Signed-off-by:

Lendacky, Thomas authored
The driver is checking the pfc_en field of the ieee_pfc structure to determine whether to associate a priority with a traffic class. This is incorrect since the pfc_en field is for determining if PFC is enabled for a traffic class. The association of priority to traffic class does not depend on whether the traffic class is enabled for PFC, so remove that check. Also, the mapping of priorities to traffic classes should be done when configuring the traffic classes and not the PFC support so move the priority to traffic class association from xgbe_config_dcb_pfc to xgbe_config_dcb_tc.

Currently the PFC flow control is enabled on all traffic classes if one or more traffic classes request it. The PFC enable setting of the traffic class should be used to determine whether to enable or disable flow control for the traffic class. Signed-off-by:

When the hardware is placed in promiscuous mode it will still perform VLAN filtering and therefore may not pass all packets to the driver. Disable all VLAN filtering when entering promiscuous mode and restore VLAN filtering upon exit from promiscuous mode. In order to avoid adding forward declarations, move the VLAN related functions earlier in the file. Signed-off-by:
