2019-06-15net: sched: remove NET_CLS_IND config optionJiri Pirko
This config option makes only couple of lines optional. Two small helpers and an int in couple of cls structs. Remove the config option and always compile this in. This saves the user from unexpected surprises when he adds a filter with ingress device match which is silently ignored in case the config option is not set.

Aleksandr adds stub functions for Energy Efficient Ethernet (EEE) to currently report that it is not supported in i40e. Fixed up the Link Layer Detection Protocol (LLDP) code to ensure we do not set the LLDP flag too early before we ensure that we have a successful start. This also will prevent needles restarting of the device if LLDP did not change its state with an unsuccessful start. Piotr bumps up the amount of VLANs that an untrusted VF can implement, from 8 VLANs to 16. Adds checks to the Virtual Embedded Bridge (VEB) and channel arrays so access does not exceed the boundary and ensure the index is below the maximum. Fixed an issue in the driver where we were not checking the response from the LLDP flag and were returned success no matter what the value of the response was. Mitch fixes a variable counter, which can be negative in value so make it an integer instead of an unsigned-integer. Doug improves the admin queue log granularity by making it possible to log only the admin queue descriptors without the entire admin queue message buffers. Sergey fixes up the virtchnl code by removing duplicate checks, ensure the variable type is correct when comparing integers, enhance error and warning messages to include useful information. Adam fixes a potential kernel panic when the i40e driver was being bound to a non-i40e port by adding a check on the BAR size to ensure it is large enough by reading the highest register. Jake fixes a statistics error in the "transmit errors" stat, which was being calculated twice. Gustavo A. R.

2019-06-14ipv4: Support multipath hashing on inner IP pkts for GRE tunnelStephen Suryaputra
Multipath hash policy value of 0 isn't distributing since the outer IP dest and src aren't varied eventhough the inner ones are. Since the flow is on the inner ones in the case of tunneled traffic, hashing on them is desired. This is done mainly for IP over GRE, hence only tested for that. But anything else supported by flow dissection should work. v2: Use skb_flow_dissect_flow_keys() directly so that other tunneling can be supported through flow dissection (per Nikolay Aleksandrov). v3: Remove accidental inclusion of ports in the hash keys and clarify the documentation (Nikolay Alexandrov).

2019-06-14virtio_net: enable napi_tx by defaultWillem de Bruijn
NAPI tx mode improves TCP behavior by enabling TCP small queues (TSQ). TSQ reduces queuing ("bufferbloat") and burstiness. Previous measurements have shown significant improvement for TCP_STREAM style workloads. Such as those in commit 86a5df1495cc ("Merge branch 'virtio-net-tx-napi'"). There has been uncertainty about smaller possible regressions in latency due to increased reliance on tx interrupts. The above results did not show that, nor did I observe this when rerunning TCP_RR on Linux 5.1 this week on a pair of guests in the same rack. This may be subject to other settings, notably interrupt coalescing. In the unlikely case of regression, we have landed a credible runtime solution. Ethtool can configure it with -C tx-frames [0|1] as of commit 0c465be183c7 ("virtio_net: ethtool tx napi configuration"). NAPI tx mode has been the default in Google Container-Optimized OS (COS) for over half a year, as of release M70 in October 2018, without any negative reports.

2019-06-14net: hns3: process H/W errors occurred before HNS dev initializationShiju Jose
Presently the HNS driver enables the HNS H/W error interrupts after the dev initialization is completed. However some exceptions such as NCSI errors can occur when the network port driver is not loaded and those errors required reporting to the BMC. Therefore the firmware enabled all the HNS ras error interrupts before the driver is loaded. And in some cases, there will be some H/W errors remained unclear before reboot. Thus the HNS driver needs to process and recover those hw errors occurred before HNS driver is initialized. This patch adds processing of the HNS hw errors(RAS and MSI-X) which occurred before the driver initialization. For RAS, because they are enabled by firmware, so we can detect specific bits, then log and clear them. But for MSI-X which can not be enabled before open vector0 irq, we can't detect the specific error bits, so we just write 1 to all interrupt source registers to clear.

2019-06-14net: hns3: fix avoid unnecessary resetting for the H/W errors which do not ↵Shiju Jose
require reset HNS does not need to be reset when errors occur in some bits. However presently the HNAE3_FUNC_RESET is set in this case and as a result the default_reset is done when these errors are reported. This patch fix this issue. Also patch does some optimization in setting the reset level for the error recovery.

2019-06-14net: hns3: delay setting of reset level for hw errors until slot_reset is calledShiju Jose
Presently the error handling code sets the reset level required for the recovery of the hw errors to the reset framework in the error_detected AER callback. However the rest_event would be called later from the slot_reset callback. This can cause issue of using the wrong reset_level if a high priority reset request occur before the slot_reset is called. This patch delays setting of the reset level, required for the hw errors, to the reset framework until the slot_reset is called.

The driver needs to assign a lossless traffic class for the MPA ll2 connection to ensure no packets are dropped when returning from the driver as they will never be re-transmitted by the peer.
