Nvidia ConnectX6 SmartNIC

I had a few questions regarding the Nvidia ConnectX6 smartNIC.

  1. Does this ethernet adapter card support base-r fec types? I have been observing blanket failures with fec_type as kr/base-r for 25GBASE_CR, 40GBASE_CR4, 50GBASE_CR2
  2. Are there any known issues while trying to get link at forced modes vs auto negotiated modes via ethtool?
