 * ice_cfg_fw_log - configure FW logging
 * @hw: pointer to the HW struct
 * @enable: enable certain FW logging events if true, disable all if false
 *
 * This function enables/disables the FW logging via Rx CQ events and a UART
 * port based on predetermined configurations. FW logging via the Rx CQ can be
 * enabled/disabled for individual PF's. However, FW logging via the UART can
 * only be enabled/disabled for all PFs on the same device.
 *
 * To enable overall FW logging, the "cq_en" and "uart_en" enable bits in
 * hw->fw_log need to be set accordingly, e.g. based on user-provided input,
 * before initializing the device.
 *
 * When re/configuring FW logging, callers need to update the "cfg" elements of
 * the hw->fw_log.evnts array with the desired logging event configurations for
 * modules of interest. When disabling FW logging completely, the callers can
 * just pass false in the "enable" parameter. On completion, the function will
 * update the "cur" element of the hw->fw_log.evnts array with the resulting
 * logging event configurations of the modules that are being re/configured. FW
 * logging modules that are not part of a reconfiguration operation retain their
 * previous states.
 *
 * Before resetting the device, it is recommended that the driver disables FW
 * logging before shutting down the control queue. When disabling FW logging
 * ("enable" = false), the latest configurations of FW logging events stored in
 * hw->fw_log.evnts[] are not overridden to allow them to be reconfigured after
 * a device reset.
 *
 * When enabling FW logging to emit log messages via the Rx CQ during the
 * device's initialization phase, a mechanism alternative to interrupt handlers
 * needs to be used to extract FW log messages from the Rx CQ periodically and
 * to prevent the Rx CQ from being full and stalling other types of control
 * messages from FW to SW. Interrupts are typically disabled during the device's
 * initialization phase.
