Detailed Description

CSI (Channel State Information) configuration.

The fields of this struct differ by target, mirroring ESP-IDF's wifi_csi_config_t:

• On Wi-Fi 4/5 targets (esp32, esp32s2, esp32s3, esp32c3), it exposes the legacy LTF/channel-filter toggles.
• On Wi-Fi 6 (HE) targets, it mirrors wifi_csi_acquire_config_t, which itself has two variants selected by SOC_WIFI_MAC_VERSION_NUM. Users writing HE-target CSI code should consult the ESP-IDF API reference for the meaning of each acquire_csi_* field.

Note

Because the field set varies by target, source code that writes to specific members is not portable across Wi-Fi 4/5 and Wi-Fi 6 targets.
