Will make sure to add to cover leter for next version but for now, Table 7-x2: Data Object Exchange ECN (first column lists the Vendor ID for the protocols) Available on the PCI SIG spec downloads page. It also exists in various other places in the 5.0 spec, but I'm not sure if any are software visible (e.g. VDMs) Jonathan > > > Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> > > --- > > Since V1: New Patch > > > > include/linux/pci_ids.h | 1 + > > 1 file changed, 1 insertion(+) > > > > diff --git a/include/linux/pci_ids.h b/include/linux/pci_ids.h > > index a76ccb697bef..2c0459c23331 100644 > > --- a/include/linux/pci_ids.h > > +++ b/include/linux/pci_ids.h > > @@ -149,6 +149,7 @@ > > #define PCI_CLASS_OTHERS 0xff > > > > /* Vendors and devices.

Please put this in the log for this commit, since the cover letter may not be merged and isn't directly connected to this commit. > Available on the PCI SIG spec downloads page. > It also exists in various other places in the 5.0 spec, but I'm > not sure if any are software visible (e.g. VDMs) > > Jonathan > > > > Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> > > > --- > > > Since V1: New Patch > > > > > > include/linux/pci_ids.h | 1 + > > > 1 file changed, 1 insertion(+) > > > > > > diff --git a/include/linux/pci_ids.h b/include/linux/pci_ids.h > > > index a76ccb697bef..2c0459c23331 100644 > > > --- a/include/linux/pci_ids.h > > > +++ b/include/linux/pci_ids.h > > > @@ -149,6 +149,7 @@ > > > #define PCI_CLASS_OTHERS 0xff > > > > > > /* Vendors and devices.
