> Allow support for 'enable_iwarp' and 'enable_roce' devlink params to turn on/off
> iWARP or RoCE protocol support for E800 devices.
> 
> For example, a user can turn on iWARP functionality with,
> 
> devlink dev param set pci/0000:07:00.0 name enable_iwarp value true cmode
> runtime
> 
> This add an iWARP auxiliary rdma device, ice.iwarp.<>, under this PF.
> 
> A user request to enable both iWARP and RoCE under the same PF is rejected since
> this device does not support both protocols simultaneously on the same port.
