Description Pau Amma 2021-11-07 21:41:46 UTC 
SYSCTL_INT(_hw_pci, OID_AUTO, do_power_nodriver, CTLFLAG_RWTUN,
    &pci_do_power_nodriver, 0,
    "Place a function into D3 state when no driver attaches to it.  0 means"
    " disable.  1 means conservatively place devices into D3 state.  2 means"
    " aggressively place devices into D3 state.  3 means put absolutely"
    " everything in D3 state.");

"function" should be "device", I think.

A PCI device may have multiple functions on a single card/device and perhaps the description is referring to that, but it does seem confusing that the first sentence mentions function and later ones mention devices.
