MAC addresses are still exposed through network interface naming

[anon-123456789]

When I upload a device probe, the raw MAC addresses of network interfaces on my system are (supposed to be) redacted. However, it seems to miss the device names, which can contain device MAC addresses in some cases.

This probably has to do with how systemd/udev handles "predictable" network interface naming: https://systemd.io/PREDICTABLE_INTERFACE_NAMES/

Example (my own computer): https://linux-hardware.org/?probe=e92f702c09&log=ip_addr

Note how the redacted version still contains the MAC address for wlp2s0 under the altname field, as wlxa483e7904326, with the actual MAC address being a4:83:e7:90:43:26. This is the same case for enp1s0f1u1 as well.
