- Teach pciconf(8) to list the PCI capabilities supported by each device
via a new -c flag to be used with -l. Some simple parsing code is
present for the following capabilities: Power Management, AGP, VPD,
MSI, PCI-X, HyperTransport, Vendor-specific, EHCI Debug Port, PCI-PCI
bridge subvendor ID, PCI-express, and MSI-X.
- Fix a few warnings in pciconf.c.
- Update some cruft in pciconf(8):
- PCI 2.1 is no longer a revolutionary standard, and subvendor ID's are
fairly common at this point, so reflect that.
- Header type 2 is used for PCI-CardBus bridges.
- Describe the -v option for -l after completing the basic -l description
instead of disrupting the flow in the middle.
