Hello Vivek,

Shouldn't this be targeting net-next (currently closed) ?
Anyway, I'm mainly replying since I'm interested in this topic and
would like to be copied in related future submissions.
Thanks,
Daniele

Hi Vivek,
This doesn't seem right.
As GCC points out, dev_addr is const.
And I don't think eth_random_addr() produces invalid addresses.
Perhaps you want eth_hw_addr_random() here.
As was mentioned elsewhere in this thread, net-next, is closed.
So please post a v2 once it re-opens, after 10th July.
