From: Yotam Gigi <[email protected]> In Spectrum, MDB entries point to MID entries, that indicate which ports a packet should be forwarded to. Add the support in creating MID entries that forward the packet to the Spectrum router port.
This will be later used to handle the bridge mrouter port switchdev notifications.
