2019-03-07qede: Fix internal loopback failure with jumbo mtu configurationSudarsana Reddy Kalluru1-2/+5
Driver uses port-mtu as packet-size for the loopback traffic. This patch limits the max packet size to 1.5K to avoid data being split over multiple buffer descriptors (BDs) in cases where MTU > PAGE_SIZE.

2019-03-07enic: fix build warning without CONFIG_CPUMASK_OFFSTACKArnd Bergmann1-3/+3
The enic driver relies on the CONFIG_CPUMASK_OFFSTACK feature to dynamically allocate a struct member, but this is normally intended for local variables. Building with clang, I get a warning for a few locations that check the address of the cpumask_var_t: drivers/net/ethernet/cisco/enic/enic_main.c:122:22: error: address of array 'enic->msix[i].affinity_mask' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion] As far as I can tell, the code is still correct, as the truth value of the pointer is what we need in this configuration. To get rid of the warning, use cpumask_available() instead of checking the pointer directly.

2019-03-07ravb: Decrease TxFIFO depth of Q3 and Q2 to oneMasaru Nagai1-1/+1
Hardware has the CBS (Credit Based Shaper) which affects only Q3 and Q2. When updating the CBS settings, even if the driver does so after waiting for Tx DMA finished, there is a possibility that frame data still remains in TxFIFO. To avoid this, decrease TxFIFO depth of Q3 and Q2 to one. This patch has been exercised this using netperf TCP_MAERTS, TCP_STREAM and UDP_STREAM tests run on an Ebisu board. No performance change was detected, outside of noise in the tests, both in terms of throughput and CPU utilisation.

2019-03-05mm: replace all open encodings for NUMA_NO_NODEAnshuman Khandual1-2/+3
Patch series "Replace all open encodings for NUMA_NO_NODE", v3. All these places for replacement were found by running the following grep patterns on the entire kernel code. Please let me know if this might have missed some instances. This might also have replaced some false positives. I will appreciate suggestions, inputs and review. 1. git grep "nid == -1" 2. git grep "node == -1" 3. git grep "nid = -1" 4. git grep "node = -1" This patch (of 2): At present there are multiple places where invalid node number is encoded as -1. Even though implicitly understood it is always better to have macros in there. Replace these open encodings for an invalid node number with the global macro NUMA_NO_NODE. This helps remove NUMA related assumptions like 'invalid node' from various places redirecting them to a common definition.

This is needed for the following scenario: - SQ has an un-recovered error reported to the devlink health, resulting tx reporter state to be error. - Current channels (including this SQ) are closed - New channels are opened After that flow, the original error was "solved", and tx reporter state should be healthy. However, as it was resolved as a side effect, and not via tx reporter recover method, driver needs to inform devlink health about it.

2019-03-03qmi_wwan: Add support for Quectel EG12/EM12Kristian Evensen1-8/+18
Quectel EG12 (module)/EM12 (M.2 card) is a Cat. 12 LTE modem. The modem behaves in the same way as the EP06, so the "set DTR"-quirk must be applied and the diagnostic-interface check performed. Since the diagnostic-check now applies to more modems, I have renamed the function from quectel_ep06_diag_detected() to quectel_diag_detected().

2019-03-03dpaa2-eth: add XDP_REDIRECT supportIoana Radulescu3-14/+176
Implement support for the XDP_REDIRECT action. The redirected frame is transmitted and confirmed on the regular Tx/Tx conf queues. Frame is marked with the "XDP" type in the software annotation, since it requires special treatment. We don't have good hardware support for TX batching, so the XDP_XMIT_FLUSH flag doesn't make a difference for now; ndo_xdp_xmit performs the actual Tx operation on the spot.

2019-03-03net: macb: Add support for suspend/resume with full power downHarini Katakam1-2/+38
When macb device is suspended and system is powered down, the clocks are removed and hence macb should be closed gracefully and restored upon resume. This patch does the same by switching off the net device, suspending phy and performing necessary cleanup of interrupts and BDs. Upon resume, all these are reinitialized again. Reset of macb device is done only when GEM is not a wake device. Even when gem is a wake device, tx queues can be stopped and ptp device can be closed (tsu clock will be disabled in pm_runtime_suspend) as wake event detection has no dependency on this.
