Hi Arend,

We noticed that brcmfmac doesn't support .del_virtual_intf for non-p2p/ap interface types.  Any chance this can be added?

We currently remove all wifi interfaces and re-create the needed ones with SOCKET_OWNER set, and it would be nice if we didn't need to treat brcmfmac specially.

This came up recently. During probe the driver creates a network interface that we refer to as primary interface. We consider this non-virtual and ownership is with the driver. My guess is that this concept comes from the WEXT era, where we did not have the ieee80211 phy objects to interact with the driver from user-space. I suppose you don't mind the creation of this interface and just want to allow removing it, right?

Regards,
Arend
