Merge branch 'remotes/lorenzo/pci/tools' (2021-09-02 14:56:52 -0500)
----------------------------------------------------------------
You should see a few conflicts:
drivers/net/ethernet/broadcom/bnxt/bnxt.c
drivers/net/ethernet/broadcom/bnx2.c
Fallout from the VPD changes below. These include both PCI core and
driver changes, and the driver changes got merged via the net tree and
then reverted so everything would be merged via the PCI tree.
