https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=278234 --- Comment #3 from Zeev Zilberman <zeev@amazon.com> --- This seems like a good reference for sysfs:

switch it looks like following: # tree -L 2 -F /sys/bus/pci* /sys/bus/pci/ ├── devices/ │ ├── 0003:00:00.0 -> ../../../devices/pci0003:00/0003:00:00.0/ │ ├── 0003:01:00.0 ->
