2018-08-30i40e: report correct statistics when XDP is enabledBjörn Töpel
When XDP is enabled, the driver will report incorrect statistics. Received frames will reported as transmitted frames. This commits fixes the i40e implementation of ndo_get_stats64 (struct net_device_ops), so that iproute2 will report correct statistics (e.g. when running "ip -stats link show dev eth0") even when XDP is enabled.

Add possibility to change a VF mac address from host side without reloading the VF driver on the guest side. Without this patch it is not possible to change the VF mac because executing i40evf_virtchnl_completion function with VIRTCHNL_OP_GET_VF_RESOURCES opcode resets the VF mac address to previous value.

2018-08-30i40evf: update ethtool stats code and use helper functionsJacob Keller
Fix a bug in the way we handled VF queues, by always showing stats for the maximum number of queues, even if they aren't allocated. It is not safe to change the number of strings reported to ethtool, as grabbing statistics occurs over multiple ethtool ops for which the rtnl_lock() cannot be held the entire time. Avoid this by always reporting queue stats for the maximum number of queues in the netdevice. Share some of the helper functionality for adding stats with the PF code in i40e_ethtool_stats.h This should reduce the chance of potential future bugs, and make adding new statistics easier. Note for the queue stats, unlike the PF driver we do not keep an array of queue pointers, but an array of queues, so care must be taken to avoid accessing queue memory that hasn't yet been allocated.

2018-08-30i40e: convert queue stats to i40e_stats arrayJacob Keller
Use an i40e_stats array to handle the queue stats, instead of coding similar functionality separately. Because of how the queue stats are accessed on some kernels, we can't easily use i40e_add_ethtool_stats. Instead, implement a separate helper, i40e_add_queue_stats, which we'll use instead. This helper will correctly implement the u64_stats_fetch_begin_irq logic and allow retries until successful. We share the most complex code by re-using i40e_add_one_ethtool_stat. This logic additionally easily supports skipping disabled rings by using a ternary operator before calling the u64_stats_fetch_begin_irq() function, so that we correctly zero-out the stats values without having to perform two separate sections of code. This significantly reduces the boiler plate code in i40e_get_ethtool_stats, and helps keep the complex logic contained to as few functions as possible. With this patch, we've finally converted all the statistics to use the helpers and the i40e_stats function.

2018-08-30scsi: iscsi: target: Fix conn_ops double freeMike Christie
If iscsi_login_init_conn fails it can free conn_ops. __iscsi_target_login_thread will then call iscsi_target_login_sess_out which will also free it. This fixes the problem by organizing conn allocation/setup into parts that are needed through the life of the conn and parts that are only needed for the login. The free functions then release what was allocated in the alloc functions. With this patch we have: iscsit_alloc_conn/iscsit_free_conn - allocs/frees the conn we need for the entire life of the conn. iscsi_login_init_conn/iscsi_target_nego_release - allocs/frees the parts of the conn that are only needed during login.

2018-08-29liquidio: improve soft command handlingFelix Manlunas
1. Set LIO_SC_MAX_TMO_MS as the maximum timeout value for a soft command (sc). All sc's use this value as a hard timeout value. Add expiry_time in struct octeon_soft_command to keep the hard timeout value. The field wait_time and timeout in struct octeon_soft_command will be obsoleted in the last patch of this patch series. 2. Add processing a synchronous sc in sc response thread lio_process_ordered_list. The memory allocated for a synchronous sc will be freed by lio_process_ordered_list() to the sc pool. 3. Add two response lists for lio_process_ordered_list to process the storage allocated for sc's: OCTEON_DONE_SC_LIST response list keeps all sc's which will be freed to the pool after their requestors have finished processing the responses. OCTEON_ZOMBIE_SC_LIST response list keeps all sc's which have got LIO_SC_MAX_TMO_MS timeout. When an sc gets a hard timeout, lio_process_order_list() will recheck its status 1 ms later. If the status has not updated by the firmware at that time, the sc will be removed from OCTEON_DONE_SC_LIST response list to OCTEON_ZOMBIE_SC_LIST response list. The sc's in the OCTEON_ZOMBIE_SC_LIST response list will be freed when the driver is unloaded.

When using the fixed PHY with GENET (e.g. MOCA) the PHY link status can be determined from the internal link status captured by the MAC. This allows the PHY state machine to use the correct link state with the fixed PHY even if MAC link event interrupts are missed when the net device is opened.

2018-08-29Revert "net: stmmac: Do not keep rearming the coalesce timer in stmmac_xmit"Jerome Brunet
This reverts commit 4ae0169fd1b3c792b66be58995b7e6b629919ecf. This change in the handling of the coalesce timer is causing regression on (at least) amlogic platforms. Network will break down very quickly (a few seconds) after starting a download. This can easily be reproduced using iperf3 for example. The problem has been reported on the S805, S905, S912 and A113 SoCs (Realtek and Micrel PHYs) and it is likely impacting all Amlogics platforms using Gbit ethernet No problem was seen with the platform using 10/100 only PHYs (GXL internal) Reverting change brings things back to normal and allows to use network again until we better understand the problem with the coalesce timer.

2018-08-29drm/i915: Increase LSPCON timeoutFredrik Schön
100 ms is not enough time for the LSPCON adapter on Intel NUC devices to settle. This causes dropped display modes at boot or screen reconfiguration. Empirical testing can reproduce the error up to a timeout of 190 ms. Basic boot and stress testing at 200 ms has not (yet) failed. Increase timeout to 400 ms to get some margin of error. Changes from v1: The initial suggestion of 1000 ms was lowered due to concerns about delaying valid timeout cases. Update patch metadata.
