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
