I am not getting onboard network connectivity to my eth port.

ifconfig and iplink only show the wireless card. How do I go about finding the driver for the ethernet port? Thanks for any tips!

Read your models entry (Dell Latitude E7470) on the Arch Wiki. Check that your BIOS is up to date. You can update your bios using fwupd.

If there is no Bios update available, then you should probably reset your bios to the factory default as this can sometimes help reactivate an improperly detected network adapter.

After resetting your bios to the factory default you will need to reset some of your bios settings for proper Linux compatibility. Be sure to disable secure boot and fastboot. Be sure all network related options are fully enabled in your bios.

Are you using Windows on this computer?

Changing kernels can often help with a multitude of issues that can occur when using Linux. Try out the linux , linux-zen and linux-mainline kernels to hopefully find some improvement.

Good luck.

Network:
  Device-1: Intel Wireless 8260 driver: iwlwifi v: kernel pcie: gen: 1
    speed: 2.5 GT/s lanes: 1 bus-ID: 01:00.0 chip-ID: 8086:24f3 class-ID: 0280

I would have thought that Device-2 is supposed to be the ethernet, since Device-1 is the wireless.
A search on linux-hardware indicates the chip-ID is that of a wireless adapter though.
I guess that's where the problem starts.
I see there are many probes for Dell Latitude E7470 Computers but they're not all the same hardware.
I hope the above can be useful to track the problem, I have no solution though.
I guess it could be solved or worked around with udev rules but... I know next to nothing about that.

I am not seeing anything for onboard networking.

I assume 02:00.0 Network Controller is the ethernet device but it shows up disabled

Not really sure how to enable it or if this can remedy my problem. It is almost like there is no driver for this device for some reason.

Thanks.

The bios is up to date. Not sure I want to go with factory orig. BIOS yet.

I am not using Windows on this computer.

I have tried Linux-lts, Linux-xanmod, Linux-tt, Linux-mainline, Linux-hardened, and Linux-cachyos-bore kernels with no change.
