[Linux-PowerEdge] Mellanox ConnectX-4 Ethernet in DSU

Good discussions came out of this thread, but no answers to my question ;-)

Last year I bought a bunch of R630, R730xd and some C4130. They were all 
configured with Mellanox ConnectX-4 from Dell and I have installed 
CentOS 7 on them.

I guess, since I bought it as a boxed solution, that Dell would support 
this network card in DSU. But not so far.

The firmware apparently has a Dell tag on them, which means that I can't 
even flash a stock Mellanox firmware on them with mstflint.

I have seen there are a few Dell guys listening to this mail list, 
perhaps they have a comment?
