If the mac address can not be read from the device registers or the

usbnet_probe, so it is not necessary to call eth_hw_addr_random from here
again to generate another random address.

Indeed, when reset was also executed from bind, generate another random mac
address invalidated the check from usbnet_probe to configure if the assigned
mac address for the interface was random or not, because it is comparing
with the initial generated random address. Now, with only a reset from open
operation, it is just a harmless simplification.

V1 -> V2:
- Split the fix and the improvement in two patches and keep curly-brackets
as Simon Horman suggests.

Hi Jose,

Thanks for splitting the patches.
They look good, but there are a few process issues.
Sorry for not being clearer in my previous email.

As the 2nd patch of the series is not a fix it:
- Should not have a fixes tag
- Should not be sent to stable
- Should be targeted at the net-next tree rather than the net tree

As the granularity of patch handling on netdev is generally at the
patchset level I believe that this means that you need to separately,
in different, new, email threads, repost:

1. Patch 1/2 of this series, targeted at net, with a Fixes tag

   [PATCH net v3] net: usb: ax88179_178a: avoid the interface always configured as random address

2. Patch 2/2 of this series, targeted at net-next, without a Fixes tag

   [PATCH net-next v3] et: usb: ax88179_178a: non necessary second random mac address

Also, please be sure to wait 24 hours since the posting of this patch-set
before reposting.
