This series adds support for Flit Mode (PCIe6). The series is built on
top of the TLP Logging refactoring series:

  https://lore.kernel.org/linux-pci/20240514113109.6690-1-ilpo.jarvinen@linux.intel.com/

Important note to maintainer: The series carries
pcie_update_link_speed() refactoring change that is almost identical
with a patch in the PCIe BW controller series. The patch itself is
basically the same but the context has minor difference. This will need
to be considered if applying both series within the same kernel cycle.

Ilpo Järvinen (3):
  PCI: Refactor pcie_update_link_speed()
  PCI: Track Flit Mode Status & print it with link status
  PCI: Handle TLP Log in Flit mode
