Do we need to define those values? Cannot you use already defined ones in
hci.h?
in include/net/bluetooth/hci.h and lib/hci.h
/* HCI controller types */
#define HCI_BREDR 0x00
#define HCI_AMP 0x01
Maybe HCI_AMP is not the best way and at some point we might need to
rename it according to BT Spec assigned numbers (like HCI_AMP_802_11)
Otherwise
