If this rule holds then there are some exceptions e.g. mvpp2 (in current release using the same version of kernel) so accepting this driver will not brake this rule any more than it is now. AFAIK Marvell is using some parts that are not upstreamable so it will be always a custom kernel - but I'm not competent enough to claim that authoritatively. In mvpp2 we have just recently switched to newer kernel (just applied to next-net) and with enough of testing mvneta will switch to it too. So I hope this is not a blocker. Best regards Andrzej
