Yes I already did it, here is my configuration:

<M>   Atheros 802.11ac wireless cards support
   │ │                                 <M>     Atheros ath10k PCI support
   │ │                                   [*]     Atheros ath10k debugging
   │ │                                   [*]     Atheros ath10k debugfs support
   │ │                                   [*]     Atheros ath10k tracing support
   │ │                                   [*]     Atheros DFS support for certified platforms

But when I check "iw list" I don't see the line like you said. But is this normal? :
