Good point, so let's assume the user doesn't have a mac stored.
Without CONFIG_NET_RANDOM_ETHADDR:
- u-boot refuses to do anything network related
- Linux generates a random mac, network works
With CONFIG_NET_RANDOM_ETHADDR:
- u-boot generates a random mac, network works
- Linux uses the same random mac, passed on from u-boot throught the
device-tree, network works
It's still random, but at least it's consistent ;)
It's also only used when we cannot find the MAC. At the end of the day, the final decision here is Konstantin's (as the listed maintainer). I personally think enabling the option is good given the apparent number of ways the real MAC will have been lost from SW, but if the maintainer wants to instead opt for a verbose failure message, that's
fine too.
I have no objections about this configuration option. It is better to have a random MAC address rather then no MAC at all.
This is also my feeling.
Kosta, can you please send a Reviewed-by or Acked-by tag then?
Thanks, Stefan
