Okay!
I'm also try ETH driver 1.9.10.5 with my MCX354A-FCBT at ETH mode with mlnxconfig.
When I boot the ESXi 6.0u2 host with SX6036G ETH port mode shows me a 56Gb Ethernet link up, but vSphere network tab shows me a 10Gb link up...:(
What do you think about it?
Does it just display incorrectly unlike SX6036G's MLNX-OS?
