two iface in one device

"K.I.R.A.
Hi , I would like to define two net ifaces in one device. Wi-Fi STA and softap are two types of ifaces at app layer, but only one device at driver layer is enough，that is only one NET_DEVICE_INIT invoked. Do you have any idea？ Best Regards, Bub |

Hi Bub,

are you talking about wifi offloading device or some out-of-tree wifi device? The NET_DEVICE_OFFLOAD_INIT() would need to be changed a bit to create more than one network interface for a given device if you have offloading wifi driver. There exists already ETH_NET_DEVICE_INIT() for ethernet which supports more than one network interface (for VLAN support) for a given device. You could see how it is doing things to create more than one network interface for a given device. Cheers, Jukka On Mon, 2018-10-29 at 14:58 +0800, "K.I.R.A. wrote:

Hi Jukka, Thanks for your response. It's not offloading driver. It's out of tree in development.

Actually, I only need do one time initialization that is for CP startup. In CP, STA and softap will be running after initializing. But now, I define two devices for STA and softap that are different models for app. In init function, I have to check if CP has been initialized by STA or softap.
