[SOLVED] Ethernet adapter completely gone after full system update

After updating (no kernel update!) and rebooting, my built-in Ethernet adapter seems to have disappeared completely. According to `ip link`, `lspci` and `lshw`, it doesn't exist. Fortunately, the integrated wireless adapter is working fine so I'm able to do stuff.
My motherboard is a Gigabyte Z790 AORUS MASTER, the Ethernet adapter in question is a Marvell AQtion AQC113C.
I've already installed the `linux-firmware-marvell` package, with no effect.
Aside from updating my system, I did not change anything about the setup. Externally, the adapter appears to be deactivated (indicators off). Might indicate a coincidental hardware failure, but I'd like to eliminate any other possibilities.

Please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

But if

According to …`lspci` … it doesn't exist.

is correct, you should check the BIOS/UEFI and test the behavior of some live-distro (grml, knoppix)
The device doesn't have to work there, but show up in lspci…

built-in Ethernet

google images shows me a pcie card, is it?
Tried to re-seat it?

Tested several live OSes, same result. Decided to double-check the BIOS settings, noticed that it says N/A under "MAC Address".
This led me to assume that the firmware is faulty, so I decided to re-flash it (and update while I'm at it). This fixed the issue.
I blame Gigabyte's crappy software.

BTW, it's not an expansion card but integrated into the rear IO. What you're seeing on Google are cards that use the same chip.
