Careful on the 9901 (64bit): with this SMU on 6.5.3 you end up with just
loopbacks, mgmt and bundle-ether interfaces as the actual interfaces are
not recognized anymore. Happened on 2 different boxes here. Rollback is

The 32-bit SMU was released back in august, there was sufficient time to
get this right. Instead the 64-bit SMU fix was just released yesterday, so
it looks like they had to rush that one.

Trivia nr 2: There is no SMU yet for the recommended releases like 7.0.2
and 6.6.3.
