And we have a bit of a mess in the names here. There are a bunch of "PCI_EXP_DEV2_*" names that would be "PCI_EXP_DEVCTL2_*" if they followed the convention. You didn't start that trend, so I'm just pointing it out in case you or Martin want to clean it up. When I add names I try to use the same name between the Linux kernel source [1] and lspci.

Yes, could you please clean it up? Otherwise it's OK. Martin
