What is the correct BlueField-2 L3 Cache size?

Hello,

according to the datasheet and the output of lscpu the BlueField-2 should have 6MB L3 cache.
When looking at the output of dmidecode it reports 12MB L3 cache.

Now when looking at the BlueField-1, there are 2 banks with 6MB L3 cache each according to the datasheet, which I suspect will be similar to the BlueField-2.

What is the correct size of the L3 for the BlueField-2?

Best,
Daniel
