Colin Ian King fixes the return value on error for the new XDP support that went into ixgbevf for 4.17. Vinicius provides a fix for queue 0 for igb, which was not receiving all the credits it needed when QAV mode was enabled. Anirudh provides several fixes for the new ice driver, starting with properly initializing num_nodes_added to zero. Fixed up a code comment to better reflect what is really going on in the code. Fixed how to detect if an OICR interrupt has occurred to a more reliable method. Md Fahad fixes the ice driver to allocate the right amount of memory when reading and storing the devices MAC addresses. The device can have up to 2 MAC addresses (LAN and WoL), while WoL is currently not supported, we need to ensure it can be properly handled when support is added. ==================== Signed-off-by: David S.

2018-04-24ice: Fix insufficient memory issue in ice_aq_manage_mac_readMd Fahad Iqbal Polash
For the MAC read operation, the device can return up to two (LAN and WoL) MAC addresses. Without access to adequate memory, the device will return an error. Fixed this by allocating the right amount of memory. Also, logic to detect and copy the LAN MAC address into the port_info structure has been added. Note that the WoL MAC address is ignored currently as the WoL feature isn't supported yet.

2018-04-24igb: Fix the transmission mode of queue 0 for Qav modeVinicius Costa Gomes
When Qav mode is enabled, queue 0 should be kept on Stream Reservation mode. From the i210 datasheet, section 8.12.19: "Note: Queue0 QueueMode must be set to 1b when TransmitMode is set to Qav." ("QueueMode 1b" represents the Stream Reservation mode) The solution is to give queue 0 the all the credits it might need, so it has priority over queue 1. A situation where this can happen is when cbs is "installed" only on queue 1, leaving queue 0 alone. For example: $ tc qdisc replace dev enp2s0 handle 100: parent root mqprio num_tc 3 \ map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 queues 1@0 1@1 2@2 hw 0 $ tc qdisc replace dev enp2s0 parent 100:2 cbs locredit -1470 \ hicredit 30 sendslope -980000 idleslope 20000 offload 1 Signed-off-by: Vinicius Costa Gomes <vinicius.gomes@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2018-04-23amd-xgbe: Improve KR auto-negotiation and trainingTom Lendacky
Update xgbe-phy-v2.c to make use of the auto-negotiation (AN) phy hooks to improve the ability to successfully complete Clause 73 AN when running at 10gbps. Hardware can sometimes have issues with CDR lock when the AN DME page exchange is being performed. The AN and KR training hooks are used as follows: - The pre AN hook is used to disable CDR tracking in the PHY so that the DME page exchange can be successfully and consistently completed. - The post KR training hook is used to re-enable the CDR tracking so that KR training can successfully complete. - The post AN hook is used to check for an unsuccessful AN which will increase a CDR tracking enablement delay (up to a maximum value). Add two debugfs entries to allow control over use of the CDR tracking workaround. The debugfs entries allow the CDR tracking workaround to be disabled and determine whether to re-enable CDR tracking before or after link training has been initiated. Also, with these changes the receiver reset cycle that is performed during the link status check can be performed less often.

2018-04-23bonding: do not set slave_dev npinfo before slave_enable_netpoll in bond_enslaveXin Long
After Commit 8a8efa22f51b ("bonding: sync netpoll code with bridge"), it would set slave_dev npinfo in slave_enable_netpoll when enslaving a dev if bond->dev->npinfo was set. However now slave_dev npinfo is set with bond->dev->npinfo before calling slave_enable_netpoll. With slave_dev npinfo set, __netpoll_setup called in slave_enable_netpoll will not call slave dev's .ndo_netpoll_setup(). It causes that the lower dev of this slave dev can't set its npinfo. One way to reproduce it: # modprobe bonding # brctl addbr br0 # brctl addif br0 eth1 # ifconfig bond0 192.168.122.1/24 up # ifenslave bond0 eth2 # systemctl restart netconsole # ifenslave bond0 br0 # ifconfig eth2 down # systemctl restart netconsole The netpoll won't really work. This patch is to remove that slave_dev npinfo setting in bond_enslave().

2018-04-23dma-mapping: postpone cpu addr translation on mmapJacopo Mondi
Postpone calling virt_to_page() translation on memory locations not guaranteed to be backed by a struct page. Try first to map memory from the device coherent memory pool, then perform translation if that fails. On some architectures, specifically SH when configured with the SPARSEMEM memory model, assuming a struct page is always assigned to a memory address lead to unexpected hangs during the virtual to page address translation. This patch fixes that specific issue but applies in the general case too.

2018-04-22s390/qeth: use Read device to query hypervisor for MACJulian Wiedmann
For z/VM NICs, qeth needs to consider which of the three CCW devices in an MPC group it uses for requesting a managed MAC address. On the Base device, the hypervisor returns a default MAC which is pre-assigned when creating the NIC (this MAC is also returned by the READ MAC primitive). Querying any other device results in the allocation of an additional MAC address. For consistency with READ MAC and to avoid using up more addresses than necessary, it is preferable to use the NIC's default MAC. So switch the the diag26c over to using a NIC's Read device, which should always be identical to the Base device.

2018-04-22s390/qeth: fix request-side race during cmd IO timeoutJulian Wiedmann
Submitting a cmd IO request (usually on the WRITE device, but for IDX also on the READ device) is currently done with ccw_device_start() and a manual timeout in the caller. On timeout, the caller cleans up the related resources (eg. IO buffer). But 1) the IO might still be active and utilize those resources, and 2) when the IO completes, qeth_irq() will attempt to clean up the same resources again. Instead of introducing additional resource locking, switch to ccw_device_start_timeout() to ensure IO termination after timeout, and let the IRQ handler alone deal with cleaning up after a request. This also removes a stray write->irq_pending reset from clear_ipacmd_list(). The routine doesn't terminate any pending IO on the WRITE device, so this should be handled properly via IO timeout in the IRQ handler.

2018-04-22s390/qeth: fix MAC address update sequenceJulian Wiedmann
When changing the MAC address on a L2 qeth device, current code first unregisters the old address, then registers the new one. If HW rejects the new address (or the IO fails), the device ends up with no operable address at all. Re-order the code flow so that the old address only gets dropped if the new address was registered successfully. While at it, add logic to catch some corner-cases.

2018-04-22s390/qeth: avoid control IO completion stallsJulian Wiedmann
For control IO, qeth currently tracks the index of the buffer that it expects to complete the next IO on each qeth_channel. If the channel presents an IRQ while this buffer has not yet completed, no completion processing for _any_ completed buffer takes place. So if the 'next buffer' is skipped for any sort of reason* (eg. when it is released due to error conditions, before the IO is started), the buffer obviously won't switch to PROCESSED until it is eventually allocated for a _different_ IO and completes. Until this happens, all completion processing on that channel stalls and pending requests possibly time out. As a fix, remove the whole 'next buffer' logic and simply process any IO buffer right when it completes. A channel will never have more than one IO pending, so there's no risk of processing out-of-sequence. *Note: currently just one location in the code really handles this problem, by advancing the 'next' index manually.

2018-04-20rapidio: fix rio_dma_transfer error handlingIoan Nicu
Some of the mport_dma_req structure members were initialized late inside the do_dma_request() function, just before submitting the request to the dma engine. But we have some error branches before that. In case of such an error, the code would return on the error path and trigger the calling of dma_req_free() with a req structure which is not completely initialized. This causes a NULL pointer dereference in dma_req_free(). This patch fixes these error branches by making sure that all necessary mport_dma_req structure members are initialized in rio_dma_transfer() immediately after the request structure gets allocated.
