-/* The chip may either have a single mode supporting any number of combinations,
- * or a fixed dual-mode (so it involves firmware loading to switch between
- * modes) setting. If there is a need to support more modes, it needs to be
- * implemented manually in WiFi HAL (see changeFirmwareMode in
- * WifiChip::handleChipConfiguration).
- *
- * Supported combinations are defined in device's makefile, for example:
- * WIFI_HAL_INTERFACE_COMBINATIONS := {{{STA, AP}, 1}, {{P2P, NAN}, 1}},
- * WIFI_HAL_INTERFACE_COMBINATIONS += {{{STA}, 1}, {{AP}, 2}}
- * What means:
- * Interface concurrency combination 1: 1 STA or AP and 1 P2P or NAN concurrent iface
- * operations.
- * Interface concurrency combination 2: 1 STA and 2 AP concurrent iface operations.
- *
- * For backward compatibility, the following makefile flags can be used to
- * generate combinations list:
- * - WIFI_HIDL_FEATURE_DUAL_INTERFACE
- * - WIFI_HIDL_FEATURE_DISABLE_AP
- * - WIFI_HIDL_FEATURE_AWARE
- * However, they are ignored if WIFI_HAL_INTERFACE_COMBINATIONS was provided.
- * With WIFI_HIDL_FEATURE_DUAL_INTERFACE flag set, there is a single mode with
- * two concurrency combinations:
- * Interface Concurrency Combination 1: Will support 1 STA and 1 P2P or NAN (optional)
- * concurrent iface operations.
- * Interface Concurrency Combination 2: Will support 1 STA and 1 AP concurrent
- * iface operations.
- *
- * The only dual-mode configuration supported is for alternating STA and AP
- * mode, that may involve firmware reloading. In such case, there are 2 separate
- * modes of operation with 1 concurrency combination each:
- * Mode 1 (STA mode): Will support 1 STA and 1 P2P or NAN (optional)
- * concurrent iface operations.
- * Mode 2 (AP mode): Will support 1 AP iface operation.
- *
- * If Aware is enabled, the concurrency combination will be modified to support either
- * P2P or NAN in place of just P2P.
