When I tried the down and up operations manually from the command line,
it worked.
But it only worked after I ran the down and up operations after the boot.
It fails to work by default after the boot for both the fresh deployment,
and for the later reboot

One thing I noticed is that the following message was printed twice
    "ax88179_178a 2-3:1.0 eth0: ax88179 - Link status is: 1"
after I ran the up operation,

Is that expected?

For details, please check the log here:

The scripts are simple, here are the two scripts for Android build:
    https://android.googlesource.com/device/linaro/dragonboard/+/refs/heads/main/shared/utils/ethaddr/ethaddr.rc
    https://android.googlesource.com/device/linaro/dragonboard/+/refs/heads/main/shared/utils/ethaddr/set_ethaddr.sh

Is the one to run the down/change mac/up operations script.

Not sure why the up in the script does not work, but works when run manually.
