Hello Steve,
Thank you for the patch.
I think a couple of improvements can be done:
1. Function existence check – if (*dev->dev_ops->mac_addr_add) – can be
taken out of the loop. We don't need to check it on each iteration.
2. I'm not completely sure, but I think loop can be started from 1, not
from 0, because mac_pool_sel[0] is always zero. Am I right?
Best regards,
Igor
