Currently after sending EAPOL frame FW transition to power saving mode
within 10 or 100 msec (as specified by power table command). According
to new requirement this timeout for a specific EAPOL frame must be
controlled by the driver by setting tx_pm_timeout field of TX_CMD to 2
(PM_FRAME_ENUM_MGMT). This value corresponds to 32 msec timeout.
