Mellanox SN2100M Mlag to Nexus Cores

[FB_23]

Hi there

I'm new to Mellanox so figuring this out.
We have a Pair of Cisco's as our Nexus Cores in a vPC. 
And I've just configured my Mlag SN2100M's for a new Storage Fabric

Now i'm trying to make the Mlag to them to our Cores.
I'm trying to use Vlan routing so i don't have to create a new scope on the Mellanox for the vlan.
I've got port 7 in a spilt-4. I get links when it's not in the Mlag channel.
I've set the spit to 10GB and set the mtu on the Mlag
But when i add the Mlag to the interface it drops.
Not sure what I'm missing to make this work.
