The disks box is drives; the net box lets you pick the interface

Disks: one row per physical drive with its model, size, temperature and IO, and a usage
bar built from the filesystems the sampler can attribute to it. Attribution is new — a
mount's source device is resolved through sysfs to the drive behind it, following one
layer of device-mapper or md and folding NVMe namespaces the way the sampler does. A pool
member gets no usage bar, because one drive's share of a raidz pool is not a real number.

Net: every interface that is up is listed and tappable, defaulting to the one that has
actually carried traffic rather than whichever the kernel listed first.
