Hrrrrm. Almost every GigE card out there has it. And yes Marvell is
OEM'ing the card.

The only thing novel about Neptune is the unusually large number of
TX/RX dma engines - to better cater to sun4v and the fact that the
number of dma engines was made asymmetric to use up their transistor
budget. Neptune has 24/16 whereas cxgb only has 8/8. I don't know
about mxge and Oplin but I'm sure they're similar.
