754 * __ew32_prepare - prepare to write to MAC CSR register on certain parts
755 * @hw: pointer to the HW structure
756 *
757 * When updating the MAC CSR registers, the Manageability Engine (ME) could
758 * be accessing the registers at the same time. Normally, this is handled in
759 * h/w by an arbiter but on some parts there is a bug that acknowledges Host
760 * accesses later than it should which could result in the register to have
761 * an incorrect value. Workaround this by checking the FWSM register which
762 * has bit 24 set while ME is accessing MAC CSR registers, wait if it is set
763 * and try again a number of times.
