From: Tristram Ha <redacted> This series of patches is to modify the original KSZ9477 DSA driver so that other KSZ switch drivers can be added and use the common code.Hi Tristram http://vger.kernel.org/~davem/net-next.html It is better to send an RFC patchset while netdev is closed and not send it to David. He will shout at you otherwise.
Noted. I really need to monitor the DSA discussion to better contribute to its success. I just found out the DSA API set_addr was removed last month due to not everybody is using it. It cited the Marvell switch was the only switch using that API and found a new way to program the MAC address. But looking at that driver I found it simply uses a randomized MAC address. For big switch with many ports where the main function is forwarding that MAC address may not matter. For small switch with 2 ports it acts more like an Ethernet controller where the switch is mainly used for daisy chaining in a ring network the MAC address can be used in feature like source address filtering.
