Someone reports there is an error message when loading rtl8156b-2 v2 04/27/23.
	r8152 6-1:1.0: ram code speedup mode fail

I don't find the same message for you.
However, I check the firmware and find some wrong content.
Could you remove /lib/firmware/rtl_nic/rtl8156b-2.fw and unplug the device.
Then, plug the device and check it again.
