We can't autoconfigure the interface until the auto configuration information is made available from the SM. The other 'correct' option is to have the kernel default the pkey to something fixed and not auto-configure based on what is in index 0. Again people will hate this this because the auto-configuration goes away, but other than that this is workable. > Create the ib0 device (netdev_register()) > Before the PKEY is set > do an ifup > do an ifdown > Set the PKEY > do an ifup. > > Not sure where to go from here.... This might be a hacky sort of solution more agreeable to all.. It does make sense that we loose carrier/etc during the pkey change. Dropping carrier will reset the IPv6 MC registrations, IIRC. Or you need to figure out if there is a better work flow around 'set mac' eg check what the ip link command does for ethernet - does it somehow refresh the IPv6 MC list automatically, or are you expected to not execute it on an up interface?
