      nfp: support Corigine PCIE vendor ID · 299ba7a3
      Yu Xiao authored
      Historically the nfp driver has supported NFP chips with Netronome's
      PCIE vendor ID. This patch extends the driver to also support NFP
      chips, which at this point are assumed to be otherwise identical from
      a software perspective, that have Corigine's PCIE vendor ID (0x1da8).
      
      Also, Rename the macro definitions PCI_DEVICE_ID_NERTONEOME_NFPXXXX
      to PCI_DEVICE_ID_NFPXXXX, as they are now used in conjunction with two
      PCIE vendor IDs.

      nfp: vendor neutral strings for chip and Corigne in strings for driver · 34e244ea
      Yu Xiao authored
      Historically the nfp driver has supported NFP chips with Netronome's
      PCIE vendor ID. In preparation for extending the to also support NFP
      chips that have Corigine's PCIE vendor ID (0x1da8) make printk statements
      relating to the chip vendor neutral.
      
      An alternate approach is to set the string based on the PCI vendor ID.
      In our judgement this proved to cumbersome so we have taken this simpler
      approach.
      
      Update strings relating to the driver to use Corigine, who have taken
      over maintenance of the driver.

      This patchset adds support for systemd defined naming scheme for port
      representors, as well as re-enables displaying PCI bus-info in ethtool.
      
      bus-info information has previously been removed from ethtool for port
      representors, as a workaround for a bug in lshw tool, where the tool would
      sometimes display wrong descriptions for port representors/PF. Now the bug
      has been fixed in lshw tool [1].
      
      Removing the workaround can be considered a regression (user might be
      running an older, unpatched version of lshw) (see [2] for discussion).
      However, calling SET_NETDEV_DEV also produces the same effect as removing
      the workaround, i.e. lshw is able to access PCI bus-info (this time not
      via ethtool, but in some other way) and the bug can occur.
      
      Adding SET_NETDEV_DEV is important, as it greatly improves netdev naming -
      - port representors are named based on PF name. Currently port representors
      are named "ethX", which might be confusing, especially when spawning VFs on
      multiple PFs. Furthermore, it's currently harder to determine to which PF
      does a particular port representor belong, as bus-info is not shown in
      ethtool.
      
      Consider the following three cases:
      
      Case 1: current code - driver workaround in place, no SET_NETDEV_DEV,
      lshw with or without fix. Port representors are not displayed because they
      don't have bus-info (the workaround), PFs are labelled correctly:
      
      $ sudo ./lshw -c net -businfo
      Bus info          Device      Class          Description
      ========================================================
      pci@0000:02:00.0  ens6f0      network        Ethernet Controller E810-XXV for SFP <-- PF
      pci@0000:02:00.1  ens6f1      network        Ethernet Controller E810-XXV for SFP
      pci@0000:02:01.0  ens6f0v0    network        Ethernet Adaptive Virtual Function <-- VF
      pci@0000:02:01.1  ens6f0v1    network        Ethernet Adaptive Virtual Function
      ...
      
      Case 2: driver workaround in place, SET_NETDEV_DEV, no lshw fix. Port
      representors have predictable names. lshw is able to get bus-info because
      of SET_NETDEV_DEV and netdevs CAN be mislabelled:
      
      $ sudo ./lshw -c net -businfo
      Bus info          Device           Class          Description
      =============================================================
      pci@0000:02:00.0  ens6f0npf0vf60   network        Ethernet Controller E810-XXV for SFP <-- mislabeled port representor
      pci@0000:02:00.1  ens6f1           network        Ethernet Controller E810-XXV for SFP
      pci@0000:02:01.0  ens6f0v0         network        Ethernet Adaptive Virtual Function
      pci@0000:02:01.1  ens6f0v1         network        Ethernet Adaptive Virtual Function
      ...
      pci@0000:02:00.0  ens6f0npf0vf26   network        Ethernet interface
      pci@0000:02:00.0  ens6f0           network        Ethernet interface <-- mislabeled PF
      pci@0000:02:00.0  ens6f0npf0vf81   network        Ethernet interface
      ...
      $ sudo ethtool -i ens6f0npf0vf60
      driver: ice
      ...
      bus-info:
      ...
      
      Output of lshw would be the same with workaround removed; it does not
      change the fact that lshw labels netdevs incorrectly, while at the same
      time it prevents ethtool from displaying potentially useful data
      (bus-info).
      
      Case 3: workaround removed, SET_NETDEV_DEV, lshw fix:
      
      $ sudo ./lshw -c net -businfo
      Bus info          Device           Class          Description
      =============================================================
      pci@0000:02:00.0  ens6f0npf0vf73   network        Ethernet Controller E810-XXV for SFP
      pci@0000:02:00.1  ens6f1           network        Ethernet Controller E810-XXV for SFP
      pci@0000:02:01.0  ens6f0v0         network        Ethernet Adaptive Virtual Function
      pci@0000:02:01.1  ens6f0v1         network        Ethernet Adaptive Virtual Function
      ...
      pci@0000:02:00.0  ens6f0npf0vf5    network        Ethernet Controller E810-XXV for SFP
      pci@0000:02:00.0  ens6f0           network        Ethernet Controller E810-XXV for SFP
      pci@0000:02:00.0  ens6f0npf0vf60   network        Ethernet Controller E810-XXV for SFP
      ...
      $ sudo ethtool -i ens6f0npf0vf73
      driver: ice
      ...
      bus-info: 0000:02:00.0
      ...
      
      In this case poort representors have predictable names, netdevs are not
      mislabelled in lshw, and bus-info is shown in ethtool.
