There's no timing in the log, so it's a bit hard to determine this, but
it looks like the device is locking up and there's nothing we can do
about it from the kernel side:

asus kernel: r8152 4-1.1:1.0 enp3s0f4u1u1: carrier on
asus kernel: r8152-cfgselector 4-1.1: Failed to read 4 bytes at 0xe820/0x0133 (-110)
asus kernel: xhci_hcd 0000:03:00.4: Timeout while waiting for setup device command
asus kernel: r8152 4-1.1:1.0 enp3s0f4u1u1: NETDEV WATCHDOG: CPU: 4: transmit queue 0 timed out 6129 ms
asus kernel: r8152 4-1.1:1.0 enp3s0f4u1u1: Tx timeout
asus kernel: xhci_hcd 0000:03:00.4: Timeout while waiting for setup device command
asus kernel: r8152-cfgselector 4-1.1: device not accepting address 4, error -62
asus kernel: r8152 4-1.1:1.0 enp3s0f4u1u1: Get ether addr fail
asus kernel: r8152-cfgselector 4-1.1: USB disconnect, device number 4

So perhaps the chip itself is the problem?

sorry it's a bit hard to determine what is really happening here but it
seems like a flaky device.  Is it overheating?

thanks,
