* i40e: Add a SW workaround for lost interruptsAnjali Singhai Jain2016-02-187-20/+40
| | | | | | | | | | | | | | | | | | This patch adds a workaround for cases where we might have interrupts that got lost but WB happened. If that happens without this patch we will see a tx_timeout. To work around it, this patch goes ahead and reschedules NAPI in that situation, if NAPI is not already scheduled. We also add a counter in ethtool to keep track of when we detect a case of tx_lost_interrupt. Note: napi_reschedule() can be safely called from process/service_task context and is done in other drivers as well without an issue.

| | | | | | | | | | | | | | Support packet split receive on VFs. This is off by default but can be enabled using ethtool private flags. Because we need to trigger a reset from outside of i40evf_main.c, create a new function to do so, and export it. Also update copyright year in file headers.

* Merge branch 'vxlan-cleanups'David S. Miller2016-02-182-130/+173

The rx processing is split between vxlan_udp_encap_recv and vxlan_rcv but in an artificial way: vxlan_rcv is just called at the end of vxlan_udp_encap_recv, continuing the rx processing where vxlan_udp_encap_recv left it. There's no clear border between those two functions. It makes sense to combine those functions into one; this will be actually needed for VXLAN-GPE where we'll need to skip part of the processing which is hard to do with the current code. However, both functions are too long already. This patchset is shortening them, consolidating extension handling that is spread all around together and moving it to separate functions. (Later patchsets will do more consolidation in other parts of the functions with the final goal of merging vxlan_udp_encap_recv and vxlan_rcv.) In process of consolidation of the extension handling, I needed to deal with vni field in a generic way, as its lower 8 bits mean different things for different extensions. While cleaning up the code to strictly distinguish between "vni" and "vni field" (which contains vni plus an additional byte), I also converted the code not to convert endianess back and forth.

| * vxlan: treat vni in metadata based tunnels consistentlyJiri Benc2016-02-181-4/+4
| | | | | | | | | | | | | | | | | | | | For metadata based tunnels, VNI is ignored when doing vxlan device lookups (because such tunnel receives all VNIs). However, this was not honored by vxlan_xmit_one when doing encapsulation bypass. Move the check for metadata based tunnel to the common place where it belongs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there are unrecognized flags present in the vxlan header, it doesn't make much sense to return the packet for further UDP processing, especially considering that for other invalid flag combinations we drop the packet because of previous checks. This means we return positive value only at the beginning of the function where tun_dst is not yet allocated. This allows us to get rid of the bad_flags and error jump labels. When we're dropping packet, we need to free tun_dst now. Signed-off-by: Jiri Benc <jbenc@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

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: David S.

Multiple code parts are going to be cut from "rocker_main.c" later on. Fix couple of checkpatch issues on the way.

|/ / | | | | | | | | | | | | | | | | | | | | No need to pass rocker_port around to alloc/free rocker functions, since they now use switchdev_trans for memory management storage. With the param removal, shorten the name of the functions since they now has nothing to do with rocker port.

(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: David S.
