2019-11-22ice: remove pointless NULL check of port_infoJacob Keller
The code in ice_sched_cleanup_all checks whether the port info is NULL prior to calling ice_sched_clear_port. However, ice_sched_clear_port already checks whether port info is non-NULL. More importantly, it also checks whether the port structure has been initialized by checking its port_state field as well.

2019-11-22ice: Refactor removal of VLAN promiscuous rulesBrett Creeley
Currently ice_clear_vsi_promisc() detects if the VLAN ID sent is not 0 and sets the recipe_id to ICE_SW_LKUP_PROMISC_VLAN in that case and ICE_SW_LKUP_PROMISC if the VLAN_ID is 0. However this doesn't allow VLAN 0 promiscuous rules to be removed, but they can be added. Fix this by checking if the promisc_mask contains ICE_PROMISC_VLAN_RX or ICE_PROMISC_VLAN_TX.

2019-11-22ice: Only disable VF state when freeing each VF resourcesAkeem G Abodunrin
It is wrong to set PF disable state flag for all VFs when freeing VF resources - Instead, we should set VF disable state flag for each VF with its resources being returned to the device. Right now, all VF opcodes, mailbox communication to clear its resources as well fails - since we already indicate that PF is in disable state, with all VFs not active. In addition, we don't need to notify VF that PF is intending to reset it, if it is already in disabled state.

2019-11-22ice: Don't modify stripping for add/del VLANs on VFBrett Creeley
Currently when adding/deleting vlans in ice_vc_process_vlan_msg() we are calling ice_vsi_manage_vlan_stripping() to enable/disable when adding and deleting a VLAN respectively. This is wrong because adding/deleting VLANs has nothing to do with configuring VLAN stripping. VLAN stripping is configured through the following VIRTCHNL operations: VIRTCHNL_OP_ENABLE_VLAN_STRIPPING VIRTCHNL_OP_DISABLE_VLAN_STRIPPING Unfortunately we can't just remove this because then stripping will never be configured on VF initialization. Fix this by adding a new function that initializes (disables/enables) VLAN stripping for the VF based on the device supported capabilities. This allows us to remove the call to ice_vsi_manage_vlan_stripping() in ice_vc_process_vlan_msg().

2019-11-22ice: Disallow VF VLAN opcodes if VLAN offloads disabledBrett Creeley
Currently if the host disables VLAN offloads on the VF by not setting the VIRTCHNL_VF_OFFLOAD_VLAN capability bit we will still honor VF VLAN configuration messages over VIRTCHNL. These messages (i.e. enable/disable VLAN stripping and VLAN filtering) should be blocked when the feature is not supported. Fix that by adding a helper function to determine if the VF is allowed to do VLAN operations based on the host's VF configuration. Also, mirror the VF communicated capabilities in the host's VF configuration.

2019-11-15net: reject PTP periodic output requests with unsupported flagsJacob Keller
Commit 823eb2a3c4c7 ("PTP: add support for one-shot output") introduced a new flag for the PTP periodic output request ioctl. This flag is not currently supported by any driver. Fix all drivers which implement the periodic output request ioctl to explicitly reject any request with flags they do not understand. This ensures that the driver does not accidentally misinterpret the PTP_PEROUT_ONE_SHOT flag, or any new flag introduced in the future. This is important for forward compatibility: if a new flag is introduced, the driver should reject requests to enable the flag until the driver has actually been modified to support the flag in question.

2019-11-08ixgbe: need_wakeup flag might not be set for TxMagnus Karlsson
The need_wakeup flag for Tx might not be set for AF_XDP sockets that are only used to send packets. This happens if there is at least one outstanding packet that has not been completed by the hardware and we get that corresponding completion (which will not generate an interrupt since interrupts are disabled in the napi poll loop) between the time we stopped processing the Tx completions and interrupts are enabled again. In this case, the need_wakeup flag will have been cleared at the end of the Tx completion processing as we believe we will get an interrupt from the outstanding completion at a later point in time. But if this completion interrupt occurs before interrupts are enable, we lose it and should at that point really have set the need_wakeup flag since there are no more outstanding completions that can generate an interrupt to continue the processing. When this happens, user space will see a Tx queue need_wakeup of 0 and skip issuing a syscall, which means will never get into the Tx processing again and we have a deadlock. This patch introduces a quick fix for this issue by just setting the need_wakeup flag for Tx to 1 all the time. I am working on a proper fix for this that will toggle the flag appropriately, but it is more challenging than I anticipated and I am afraid that this patch will not be completed before the merge window closes, therefore this easier fix for now. This fix has a negative performance impact in the range of 0% to 4%. Towards the higher end of the scale if you have driver and application on the same core and issue a lot of packets, and towards no negative impact if you use two cores, lower transmission speeds and/or a workload that also receives packets.

2019-11-08igb/igc: use ktime accessors for skb->tstampJacob Keller
When implementing launch time support in the igb and igc drivers, the skb->tstamp value is assumed to be a s64, but it's declared as a ktime_t value. Although ktime_t is typedef'd to s64 it wasn't always, and the kernel provides accessors for ktime_t values. Use the ktime_to_timespec64 and ktime_set accessors instead of directly assuming that the variable is always an s64. This improves portability if the code is ever moved to another kernel version, or if the definition of ktime_t ever changes again in the future.

2019-11-08iavf: initialize ITRN registers with correct valuesNicholas Nunley
Since commit 92418fb14750 ("i40e/i40evf: Use usec value instead of reg value for ITR defines") the driver tracks the interrupt throttling intervals in single usec units, although the actual ITRN registers are programmed in 2 usec units. Most register programming flows in the driver correctly handle the conversion, although it is currently not applied when the registers are initialized to their default values. Most of the time this doesn't present a problem since the default values are usually immediately overwritten through the standard adaptive throttling mechanism, or updated manually by the user, but if adaptive throttling is disabled and the interval values are left alone then the incorrect value will persist. Since the intended default interval of 50 usecs (vs. 100 usecs as programmed) performs better for most traffic workloads, this can lead to performance regressions. This patch adds the correct conversion when writing the initial values to the ITRN registers.

2019-11-08ice: Use ice_ena_vsi and ice_dis_vsi in DCB configuration flowAnirudh Venkataramanan
DCB configuration flow needs to disable and enable only the PF (main) VSI, so use ice_ena_vsi and ice_dis_vsi. To avoid the use of ifdef to control the staticness of these functions, move them to ice_lib.c. Also replace the allocate and copy of old_cfg to kmemdup() in ice_pf_dcb_cfg().

2019-11-07net: ethernet: intel: Demote MTU change prints to debugFlorian Fainelli
Changing a network device MTU can be a fairly frequent operation, and failure to change the MTU is reflected to user-space properly, both by an appropriate message as well as by looking at whether the device's MTU matches the configuration. Demote the prints to debug prints by using netdev_dbg(), making all Intel wired LAN drivers consistent, since they used a mixture of PCI device and network device prints before.

When the device is not capable of supporting SR-IOV -ENODEV is being returned; -EOPNOTSUPP is more appropriate.

2019-11-06ice: Rename VF function ice_vc_dis_vf to match its behaviorBrett Creeley
ice_vc_dis_vf() tells iavf that it's going to perform a reset and then performs a software reset. This is misleading based on the function name because the VF does not get disabled. So fix this by changing the name to ice_vc_reset_vf().

2019-11-06ice: write register with correct offsetMitch Williams
The VF_MBX_ARQLEN register array is per-PF, not global, so we should not use the absolute VF ID as an index. Instead, use the per-PF VF ID. This fixes an issue with VFs on PFs other than 0 not seeing reset.
