Description (partial)

For fixed SFP interfaces neither FXOS CLI nor GUI allow to change Auto Negotiation option for fixed SFP+ ports.
For Gigabit interfaces auto-negotiation must be enabled as required in the standard and cannot be disabled.
When Firepower appliance is connected to another one which doesn't allow to enable negotiation they will not be able to communicate and additional hardware will be required.
Auto Negotiation option is not properly explained in FTD/FXOS documentation.
