10-Bit Tag capability, introduced in PCIe-4.0 increases the total Tag field size from 8 bits to 10 bits. This patchset is to enable 10-Bit tag for PCIe EP devices (include VF) and RP devices. V1->V2: Fix some comments by Christoph. - Store the devcap2 value in the pci_dev instead of reading it multiple times. - Change pci_info to pci_dbg to avoid the noisy log. - Rename ext_10bit_tag_comp_path to ext_10bit_tag. - Fix the compile error. - Rebased on v5.13-rc1.
