2016-02-29i40e: Add support for client interface for IWARP driverAnjali Singhai Jain
This patch adds a Client interface for i40iw driver support. Also expands the Virtchannel to support messages from i40evf driver on behalf of i40iwvf driver. This client API is used by the i40iw and i40iwvf driver to access the core driver resources brokered by the i40e driver.

2016-02-19i40e: queue-specific settings for interrupt moderationKan Liang
For i40e driver, each vector has its own ITR register. However, there are no concept of queue-specific settings in the driver proper. Only global variable is used to store ITR values. That will cause problems especially when resetting the vector. The specific ITR values could be lost. This patch move rx_itr_setting and tx_itr_setting to i40e_ring to store specific ITR register for each queue. i40e_get_coalesce and i40e_set_coalesce are also modified accordingly to support queue-specific settings. To make it compatible with old ethtool, if user doesn't specify the queue number, i40e_get_coalesce will return queue 0's value. While i40e_set_coalesce will apply value to all queues.

2016-02-18i40e/i40evf: Move Tx checksum closer to TSOAlexander Duyck
On all of the other Intel drivers we place checksum close to TSO as they have a significant amount in common and it can help to reduce the decision tree for how to handle the frame as the first check in TSO is to see if checksumming is offloaded, and if it is not we can skip _BOTH_ TSO and Tx checksum offload based on a single check.

2016-02-18i40e/i40evf: Rewrite logic for 8 descriptor per packet checkAlexander Duyck
This patch is meant to rewrite the logic for how we determine if we can transmit the frame or if it needs to be linearized. The previous code for this function was using a mix of division and modulus division as a part of computing if we need to take the slow path. Instead I have replaced this by simply working with a sliding window which will tell us if the frame would be capable of causing a single packet to span several descriptors. The logic for the scan is fairly simple. If any given group of 6 fragments is less than gso_size - 1 then it is possible for us to have one byte coming out of the first fragment, 6 fragments, and one or more bytes coming out of the last fragment. This gives us a total of 8 fragments which exceeds what we can allow so we send such frames to be linearized. Arguably the use of modulus might be more exact as the approach I propose may generate some false positives. However the likelihood of us taking much of a hit for those false positives is fairly low, and I would rather not add more overhead in the case where we are receiving a frame composed of 4K pages.

For this reason I am splitting up the descriptor count function from the function that stops the ring. Also in order to try and reduce unnecessary duplication of code I am moving the slow-path portions of the code out of being inline calls so that we can just jump to them and process them instead of having to build them into each function that calls them.

2016-02-18i40e/i40evf: Do not write to descriptor unless we completeAlexander Duyck
This patch defers writing to the Tx descriptor bits until we know we have successfully completed a given operation. So for example we defer updating the tunnelling portion of the context descriptor until we have fully identified the type. The advantage to this approach is that we can assemble values as we go instead of having to try and kludge everything together all at once. As a result we can significantly clean up the tunneling configuration for instance as we can just do a pointer walk and do the math for the distance between each set of points.

Second was the fact that we cleared the flag for v4 going to v6, but we didn't take care of txflags going the other way. As such we would have the v6 flag still set even if the inner header was v4.

2016-02-18i40e/i40evf: Replace header pointers with unions of pointers in Tx checksum pathAlexander Duyck
The Tx checksum path was maintaining a set of 3 pointers and two lengths in order to prepare the packet for being checksummed. The thing is we only really needed 2 pointers, and the lengths that were being maintained can easily be computed. As such we can replace the IPv4 and IPv6 header pointers with one single union that represents both, or a generic pointer to the start of the network header. For the L4 headers we can do the same with TCP and a generic pointer to the start of the transport header. The length of the TCP header is obtained by simply multiplying doff by 4, and the network header length can be obtained by subtracting the network header pointer from the transport header pointer. While I was at it I renamed l4_hdr to l4_proto to make it a bit more clear and less likely to be confused with l4.hdr which is the transport header pointer.

This patch goes through and pulls all of the spots where we were updating either the TCP or IP checksums in the TSO and checksum path into the TSO function. The general idea here is that we should only be updating the header after we verify we have completed a skb_cow_head check to verify the head is writable. One other advantage to doing this is that it makes things much more obvious. For example, in the case of IPv6 there was one spot where the offset of the IPv4 header checksum was being updated which is obviously incorrect.

2016-02-18i40e/i40evf: Factor out L4 header and checksum from L3 bits in TSO pathAlexander Duyck
This patch makes it so that the L4 header offsets and such can be ignored when dealing with the L3 checksum and length update. This is done making use of two things. First we can just use the offset from the L4 header to the start of the packet to determine the L4 offset, and from that we can then make use of the data offset to determine the full length of the headers. As far as adjusting the checksum to remove the length we can simply add the inverse of the length instead of having to recompute the entire pseudo-header without the length. In the case of an IPv6 header this should be significantly cheaper since we can make use of a value we already needed instead of having to read the source and destination address out of the packet.

2016-02-18i40e/i40evf: Drop outer checksum offload that was not requestedAlexander Duyck
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: Removal of code which relies on BASE VEB SEIDKiran Patil
Fixed mapping of SEID is removed from specification. Hence this patch removes code which was using hard coded base VEB SEID. Changed FCoE code to use "hw->pf_id" to obtain correct "idx" and verified. Removed defines for BASE VSI/VEB SEID and BASE_PF_SEID since it is not used anymore.

2016-02-17i40e: Fix PROMISC mode for Multi-function per port (MFP) devicesAnjali Singhai Jain
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.

2016-02-17i40e: Add a SW workaround for lost interruptsAnjali Singhai Jain
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.

Get rid of the unused hsplit field in the ring struct and use the existing macro to detect packet split enablement. This allows debugfs dumps of the VSI to properly show which Rx routine is in use.
