Prevent repeated conversions from and to network order in the fast path. To achieve this, define all flag constants in big endian order and store VNI as __be32. To prevent confusion between the actual VNI value and the VNI field from the header (which contains additional reserved byte), strictly distinguish between "vni" and "vni_field". Signed-off-by:

Currently, pointer to the vxlan header is kept in a local variable. It has to be reloaded whenever the pskb pull operations are performed which usually happens somewhere deep in called functions. Create a vxlan_hdr function and use it to reference the vxlan header instead. Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-02-17 This series contains updates to i40e/i40evf only (again). Jesse moves sync_vsi_filters() up in the service_task because it may need to request a reset, and we do not want to wait another round of service task time. Refactored the enable_icr0() in order to allow it to be decided by the caller whether the CLEARPBA (clear pending events) bit will be set while re-enabling the interrupt. Also provides the "Don't Give Up" patch, where the driver will keep polling trying to allocate receive buffers until it succeeds. This should keep all receive queues running even in the face of memory pressure. Cleans up the debugging helpers by putting everything in hex to be consistent. Neerav updates the DCB firmware version related checkes specific to X710 and XL710 only since the checks are not required for X722 devices. Shannon adds the use of the new shared MAC filter bit for multicast and broadcast filters in order to make better use of the filters available from the device. Added a parameter to allow the driver to set the enable/disable of statistics gathering in the hardware switch. Also the L2 cloud filtering parameter is removed since it was never used. Anjali refactors the force_wb and WB_ON_ITR functionality since Force-WriteBack functionality in X710/XL710 devices has been moved out of the clean routine and into the service task, so we need to make sure WriteBack-On-ITR is separated out since it is still called from clean. Catherine changes the VF driver string to reflect all the products that are supported. Mitch refactors the packet split receive code to properly use half-pages for receives. Also changes the use of bitwise operators to logical operators on clean_complete variable, while making a witty reference to Mr. Spock. Cleans up (i.e. removes) the hsplit field in the ring structure and use the existing macro to detect packet split enablement, which allows debugfs dumps of the VSI to properly show which recevie routine is in use. ==================== Signed-off-by: -

Jiri Pirko says: ==================== rocker: do world split This patchset allows new rocker worlds to be easily added in future. Two new worlds are now under development: P4 and eBPF. The main part of the patchset is the OF-DPA carve-out. It resuts in OF-DPA specific file. Clean cut. Note this patchset is based on my original attempt in October 2015. I had to rebase, included all suggestions and did lot of small changes. Main change to go with all-port-one-world approach. Port world is set according to what is setup in HW. Not possible to change worlds from driver. v1->v2: patch 12/13: - split port_init into pre-init and init ==================== Signed-off-by: -

Carve out OF-DPA would specific code from the common file to the world file. This change required struct rocker and struct rocker_port split into world specific struct ofdpa and struct ofdpa_port. Along with this the world specific functions and defines were renamed from prefix "rocker_" to "ofdpa_". Signed-off-by:

The only purpose of passing this parameter is to check for prepare phase. The only reason for a failure in that state is if TLVs don't fit into descriptor. That is highly unlikely and if that happens, it is a driver bug. So remove this parameter from rocker_cmd_exec, and check for prepare phase in caller. Signed-off-by:

Since "rocker.c" is going to be split into multiple files, start with renaming original "rocker.c" file to "rocker_main.c". Multiple code parts are going to be cut from "rocker_main.c" later on. Fix couple of checkpatch issues on the way. Signed-off-by:

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.

Mr. Spock would certainly raise an eyebrow to see us using bitwise operators, when we should clearly be relying on logic. Fascinating. Change-ID: Ie338010c016f93e9faa2002c07c90b15134b7477 Signed-off-by:

Refactor the packet split Rx code to properly use half-pages for receives. The previous code was doing way more mapping and unmapping than it needed to, and wasn't properly using half-pages. Increment the page use count each time we give a half-page to an skb, knowing that the stack will probably process and release the page before we need it again. Only free and reallocate pages if the count shows that both half-pages are in use. Add counters to track reallocations and page reuse.

This is the "Don't Give Up" patch. Previously the driver could fail an allocation, and then possibly stall a queue forever, by never coming back to continue receiving or allocating buffers. With this patch, the driver will keep polling trying to allocate receive buffers until it succeeds. This should keep all receive queues running even in the face of memory pressure. Also update copyright year in file header. Change-ID: I2b103d1ce95b9831288a7222c3343ffa1988b81b Signed-off-by:

While re-enabling interrupts the driver would clear all pending causes. This meant that if an interrupt was generated while the driver was cleaning or polling with interrupts disabled, then that interrupt was lost. This could cause a queue to become dead, especially for receive. Refactored the enable_icr0 function in order to allow it to be decided by the caller whether the CLEARPBA (clear pending events) bit will be set while re-enabling the interrupt. Also update copyright year in file headers. Change-ID: Ic1db100a05e13c98919057696db147a258ca365a Signed-off-by:

Now that the Force-WriteBack functionality in X710/XL710 devices has been moved out of the clean routine and into the service task, we need to make sure WriteBack-On-ITR is separated out since it is still called from clean. In the X722 devices, Force-WriteBack implies WriteBack-On-ITR but without the interrupt, which put the driver into a missed interrupt scenario and a potential tx-timeout report. With this patch, we break the two functions out, and call the appropriate ones at the right place. This will avoid creating missed interrupt like scenarios for X722 devices. Also update copyright year in file headers. Change-ID: Iacbde39f95f332f82be8736864675052c3583a40 Signed-off-by:

With the latest firmware, statistics gathering can now be enabled and disabled in the HW switch, so we need to add a parameter to allow the driver to set it as desired. At the same time, the L2 cloud filtering parameter has been removed as it was never used. Older drivers working with the newer firmware and newer drivers working with older firmware will not run into problems with these bits as the defaults are reasonable and there is no overlap in the bit definitions. Also, newer drivers will be forced to update because of the change in function call parameters, a reminder that the functionality exists. Also update copyright year.

Add the use of the new Shared MAC filter bit for multicast and broadcast filters in order to make better use of the filters available from the device. The FW folks have assured me that setting this bit on older FW will have no affect, so we don't need a version check. Also fixed a stray indent problem nearby. Also update copyright year.
