2016-02-18i40e: add adminq commands for Rx CTL registersShannon Nelson1-0/+16
Add the new opcodes and struct used for asking the firmware to update Rx control registers that need extra care when being accessed while under heavy traffic - e.g. sustained 64byte packets at line rate on all ports. The firmware will take extra steps to be sure the register accesses are successful.

2016-02-18i40e/i40evf: Move Tx checksum closer to TSOAlexander Duyck1-5/+5
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 Duyck2-46/+78
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.

2016-02-18i40e/i40evf: Break up xmit_descriptor_count from maybe_stop_txAlexander Duyck2-50/+56
In an upcoming patch I would like to have access to the descriptor count used for the data portion of the frame. 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.

2016-02-18i40evf: Update feature flags to reflect newly enabled featuresAlexander Duyck1-4/+19
Recent changes should have enabled support for IPv6 based tunnels and support for TSO with outer UDP checksums. As such we can update the feature flags to reflect that. In addition we can clean-up the flags that aren't needed such as SCTP and RXCSUM since having the bits there doesn't add any value. I also found one spot where we were setting the same flag twice. It looks like it was probably a git merge error that resulted in the line being duplicated. As such I have dropped it in this patch.

2016-02-18i40e/i40evf: Do not write to descriptor unless we completeAlexander Duyck1-38/+42
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.

2016-02-18i40e/i40evf: Add support for IPv4 encapsulated in IPv6Alexander Duyck1-15/+26
This patch fixes two issues. First was the fact that iphdr(skb)->protocl was being used to test for the outer transport protocol. This completely breaks IPv6 support. 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 Duyck1-26/+26
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.

2016-02-18i40e/i40evf: Consolidate all header changes into TSO functionAlexander Duyck1-18/+26
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 Duyck1-13/+18
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 Duyck2-42/+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.

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.

2016-02-16i40evf: enable bus master after resetMitch Williams1-0/+1
If the VF is reset via VFLR, the device will be knocked out of bus master mode, and the driver will fail to recover from the reset. Fix this by enabling bus mastering after every reset. In a non-VFLR case, the bus master bit will not be disabled, and this call will have no effect.

2016-02-16i40e: fix write-back-on-itr to work with legacy itrAnjali Singhai Jain1-1/+2
We were not doing write-back on interrupt throttle for Legacy case in X722. This patch fixes that, so we do WB_ON_ITR for Legacy as well. Plus the issue that we should still be setting NO_ITR if we are touching the DYN_CTLN register since we do not want to change ITR setting here.
