Use PCI_EXP_LNKCAP_SLS_2_5GB and PCI_EXP_LNKCAP_SLS_5_0GB instead of hardcoded values for readability. These bit definitions were added by commit 130f1b8 ("PCI: Add PCIe Link Capability link speed and width names")

I posted the same patch last month, along with two other patches that fix the reporting for pre-r3.0 devices and simplify the code a bit:
http://marc.info/?l=linux-pci&m=135732663513525&w=2 http://marc.info/?l=linux-pci&m=135732713413779&w=2 http://marc.info/?l=linux-pci&m=135732666213542&w=2
Oh, I missed your patch. I think that my patch will be abandoned.
Best regards, Jingoo Han
I don't know the status of any of these; I'm expecting Dave to do whatever he thinks is best.
