2016-02-18i40e/i40evf: Drop outer checksum offload that was not requestedAlexander Duyck3-45/+5
The i40e and i40evf drivers contained code for inserting an outer checksum on UDP tunnels. The issue however is that the upper levels of the stack never requested such an offload and it results in possible errors. In addition the same logic was being applied to the Rx side where it was attempting to validate the outer checksum, but the logic there was incorrect in that it was testing for the resultant sum to be equal to the header checksum instead of being equal to 0. Since this code is so massively flawed, and doing things that we didn't ask for it to do I am just dropping it, and will bring it back later to use as an offload for SKB_GSO_UDP_TUNNEL_CSUM which can make use of such a feature. As far as the Rx feature I am dropping it completely since it would need to be massively expanded and applied to IPv4 and IPv6 checksums for all parts, not just the one that supports Tx checksum offload for the outer.

2016-02-17i40e: When in promisc mode apply promisc mode to Tx Traffic as wellAnjali Singhai Jain2-2/+10
In MFP mode particularly when we were setting the PF VSI in limited promiscuous, the HW switch was still mirroring the outgoing packets from other VSIs (VF/VMdq) onto the PF VSI. With this new bit set, the mirroring doesn't happen any more and so we are in limited promiscuous on the PF VSI in MFP which is similar to defport. An API check is not required, since this bit is reserved for FW API version < 1.5 Also update copyright year in file headers.

2016-02-17i40e: Do not disable queues in the Legacy/MSI Interrupt handlerAnjali Singhai Jain2-23/+6
The queues should never be enabled/disabled in the interrupt handler, ICR0 interrupt enable should be the only thing that needs to be dynamically changed in the handler. This patch fixes that. Without this patch X722 platforms were seeing weird ping timings when in Legacy mode since it takes a whole lot of time for the HW/FW to re-enable queues.

2016-02-17i40e/i40evf: avoid atomicsMitch Williams1-8/+13
In the case where we have a page fully used by receive data, we need to release the page fully to the stack. Instead of calling get_page (which increments the page count) followed by free_page (which decrements the page count), just donate our reference to the stack. Although this donation is not tax deductible, it does allow us to avoid two very expensive atomic operations that reverse each other.

This patch falls back to enabling unicast, multicast and broadcast promiscuous mode when the driver must disable it's use of "default port" aka defport mode (which is normally used to provide a promiscuous mode), due to internal incompatibility with Multiple Function per Port (aka MFP). The situation that requires this patch is when Physical Function 0 is the device being used, and it can support SR-IOV when MFP is enabled, via the driver creating a VEB on an MFP enabled adapter.

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.

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.

2016-02-17i40e/i40evf: don't lose interruptsJesse Brandeburg4-11/+17
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.

2016-02-17i40e: Refactor force_wb and WB_ON_ITR functionality codeAnjali Singhai Jain1-23/+34
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.

Jesse refactors the DCB function based on a community suggestion to change the multi-level if statement into a switch statement. Cleans up VF device IDs in the PF, since it does not need to know them. ==================== Signed-off-by: David S. Miller <[email protected]>
2016-02-17net: rework setup_tc ndo op to consume general tc operandJohn Fastabend2-5/+8
This patch updates setup_tc so we can pass additional parameters into the ndo op in a generic way. To do this we provide structured union and type flag. This lets each classifier and qdisc provide its own set of attributes without having to add new ndo ops or grow the signature of the callback.

2016-02-17net: rework ndo tc op to consume additional qdisc handle parameterJohn Fastabend3-7/+14
The ndo_setup_tc() op was added to support drivers offloading tx qdiscs however only support for mqprio was ever added. So we only ever added support for passing the number of traffic classes to the driver. This patch generalizes the ndo_setup_tc op so that a handle can be provided to indicate if the offload is for ingress or egress or potentially even child qdiscs.

2016-02-16i40e: remove VF device IDs from PFJesse Brandeburg2-12/+0
The PF doesn't need to know about the VF's device IDs, so remove them.

2016-02-16i40e: add netdev info to VSI dumpShannon Nelson1-8/+16
Add a few more bits of netdev data into the debugfs output for dump VSI. For now, we'll add the features, hw_features, vlan_features, and flags bitflags and the state. More could be added later if needed. Also, tweak a couple nearby output lines for output readability.
