There are a lot of codes that searches PCI express capability offset

in the struct pci_dev will reduce unncecessary search. This patch adds
an additional 'pcie_cap' fields into struct pci_dev, which is
initialized at pci device scan time (in set_pcie_port_type()).
I think adding this should imply the removal of ->is_pcie. pcie_cap == 0
means !is_pcie.
Right.
But, as you know, we need to change users of is_pcie (including some
adapter card drivers) before removing it.
Thanks,
