AE_NOT_FOUND (20221020/psargs-503) question

Hi,

After resuming from system suspend, the Ethernet interface provided via 
the Thunderbolt 3 connection through the Razer Core X Chroma is not 
reinitializing properly. I'm attempting to bring it back online.

 1. *Laptop* is the *host* (upstream TB3 device)
 2. *Monitor* has both *upstream* (connected to laptop) and *downstream*
    (connected to eGPU) Thunderbolt ports


                                    Thunderbolt upstream
|   Laptop      |=======================> | Thunderbolt Monitor |
|  (TB3 Host) |                      |
                                  |

               Thunderbolt downstream

                      |    eGPU         |
                      |  enclosure   |


dmesg logs when resuming the system
