AES-CCMP KEY only support 128BIT?

[webrtcccccc]

Dear Newracom,

The default of nrc_wifi_softap_set_conf() is to set pairwise to CCMP. CCMP in wpa_cli means that AES128.
[ctrl_iface_receive_response] cmd: set_network 0 pairwise CCMP
[ctrl_iface_receive_response] cmd: set_network 0 group CCMP

I manually set pairwise to CCMP-256. WIFI can connect successfully but shows some RX errors. Does AES-CCMP KEY only support 128BIT?

Code
ctrl_iface_receive_response(0, "set_network 0 pairwise CCMP-256");
ctrl_iface_receive_response(0, "set_network 0 group CCMP-256");
