      net: hns3: add support for multiple media type · 88d10bd6
      Jian Shen authored
      Previously, we can only identify copper and fiber type, the
      supported link modes of port information are always showing
      SR type. This patch adds support for multiple media types,
      include SR, LR CR, KR. Driver needs to query the media type
      from firmware periodicly, and updates the port information.
      
      The new port information looks like this:
      Settings for eth0:
              Supported ports: [ FIBRE ]
              Supported link modes:   25000baseCR/Full
                                      25000baseSR/Full
                                      1000baseX/Full
                                      10000baseCR/Full
                                      10000baseSR/Full
                                      10000baseLR/Full
              Supported pause frame use: Symmetric
              Supports auto-negotiation: No
              Supported FEC modes: None BaseR
              Advertised link modes:  Not reported
              Advertised pause frame use: No
              Advertised auto-negotiation: No
              Advertised FEC modes: Not reported
              Speed: 10000Mb/s
              Duplex: Full
              Port: FIBRE
              PHYAD: 0
              Transceiver: internal
              Auto-negotiation: off
              Current message level: 0x00000036 (54)
                                     probe link ifdown ifup
              Link detected: yes
      
      In order to be compatible with old firmware which only support
      sfp speed, we remained using the same query command, and kept
      the former logic.

      usbnet: ipheth: Remove unnecessary NULL pointer check · e28441e2
      Guenter Roeck authored
      ipheth_carrier_set() is called from two locations. In
      ipheth_carrier_check_work(), its parameter 'dev' is set with
      container_of(work, ...) and can not be NULL. In ipheth_open(),
      dev is extracted from netdev_priv(net) and dereferenced before
      the call to ipheth_carrier_set(). The NULL pointer check of dev
      in ipheth_carrier_set() is therefore unnecessary and can be removed.

      Allow an interrupt number to be passed in the platform data. The
      driver will then use it if not zero, otherwise it will poll for
      interrupts.

      mv88e6xxx: Disable ports to save power
      
      Save some power by disabling ports. The first patch fully disables a
      port when it is runtime disabled. The second disables any ports which
      are not used at all.
      
      Depending on configuration strapping, this can lower the temperature
      of an idle switch a few degrees.

      net: dsa :mv88e6xxx: Disable unused ports · 100a9b9d
      Andrew Lunn authored
      If the NO_CPU strap is set, the switch starts in 'dumb hub' mode, with
      all ports enable. Ports which are then actively used are reconfigured
      as required when the driver starts. However unused ports are left
      alone. Change this to disable them, and turn off any SERDES
      interface. This could save some power and so reduce the temperature a
      bit.

      ====================
      40GbE Intel Wired LAN Driver Updates 2019-05-03
      
      This series contains updates to the i40e driver only.
      
      Carolyn changes the driver behavior to now disable the VF after one MDD
      event instead of allowing a couple of MDD events before doing the reset.
      
      Aleksandr changes the driver to only report an error when a VF tries to
      remove VLAN when a port VLAN is configured, unless it is VLAN 0.  Also
      extends the LLDP support to be able to keep the current LLDP state
      persistent across a power cycle.
      
      Maciej fixes the checksum calculation due to firmware changes, which
      requires the driver to perform a double shadow RAM dump in some cases.
      
      Adam adds advertising support for 40GBase_LR4, 40GBase_CR4 and fibre in
      the driver.
      
      Jake cleans up a check that is not needed and was producing a warning in
      GCC 8.
      
      Harshitha fixes a misleading message by ensuring that a success message
      is only printed on the host side when the promiscuous mode change has
      been successful.
      
      Stefan Assmann adds the vendor id and device id to the dmesg log entry
      during probe to help with bug reports when lspci output may not be
      available.
      
      Alice and Piotr add recovery mode support in the i40e driver, which is
      needed for migrating from a structured to a flat firmware image.
      
      v2: Removed patch 1 "i40e: replace switch-statement to speed-up
          retpoline-enabled builds" from the series since it is no longer
          needed.  Also updated the last patch in the series that introduces
          recovery mode support, to include a more detailed patch description
          and removed code not intended for the upstream kernel.

       "This is mostly io_uring fixes/tweaks. Most of these were actually done
        in time for the last -rc, but I wanted to ensure that everything
        tested out great before including them. The code delta looks larger
        than it really is, as it's mostly just comment additions/changes.
      
        Outside of the comment additions/changes, this is mostly removal of
        unnecessary barriers. In all, this pull request contains:
      
         - Tweak to how we handle errors at submission time. We now post a
           completion event if the error occurs on behalf of an sqe, instead
           of returning it through the system call. If the error happens
           outside of a specific sqe, we return the error through the system
           call. This makes it nicer to use and makes the "normal" use case
           behave the same as the offload cases. (me)
      
         - Fix for a missing req reference drop from async context (me)
      
         - If an sqe is submitted with RWF_NOWAIT, don't punt it to async
           context. Return -EAGAIN directly, instead of using it as a hint to
           do async punt. (Stefan)
      
         - Fix notes on barriers (Stefan)
      
         - Remove unnecessary barriers (Stefan)
      
         - Fix potential double free of memory in setup error (Mark)
      
         - Further improve sq poll CPU validation (Mark)
      
         - Fix page allocation warning and leak on buffer registration error
           (Mark)
      
         - Fix iov_iter_type() for new no-ref flag (Ming)

      PCI/LINK: Add Kconfig option (default off) · 2078e1e7
      Keith Busch authored
      e8303bb7 ("PCI/LINK: Report degraded links via link bandwidth
      notification") added dmesg logging whenever a link changes speed or width
      to a state that is considered degraded.  Unfortunately, it cannot
      differentiate signal integrity-related link changes from those
      intentionally initiated by an endpoint driver, including drivers that may
      live in userspace or VMs when making use of vfio-pci.  Some GPU drivers
      actively manage the link state to save power, which generates a stream of
      messages like this:
      
        vfio-pci 0000:07:00.0: 32.000 Gb/s available PCIe bandwidth, limited by 2.5 GT/s x16 link at 0000:00:02.0 (capable of 64.000 Gb/s with 5 GT/s x16 link)
      
      Since we can't distinguish the intentional changes from the signal
      integrity issues, leave the reporting turned off by default.  Add a Kconfig
      option to turn it on if desired.
