struct cmd_ds_802_11_ps_mode contains the command header and a pointer to it was initialized with data points to the body which leads to mis-interpretation of the cmd_ds_802_11_ps_mode.action member. cmd[0] contains the header, &cmd[1] points beyond that. cmdnode->cmdbuf is a pointer to the command buffer This piece of code was unused since power saving was not enabled.
