Hello,
Does a break out cable which is known to work with connectx 5 should work out of te box without furteher setting (like ethtool) ? I am referring to a 100 GB cable with 4 x 25 ends, which connects a dual port connectx-5 nic to I40E .

Or does it require setting or flushing firmware with tools like flint, mlxconfig, mlxcable, etc ,?

Regards,
Kevin
