The following operations can be performed when the MAC receives the LPI pattern from the PHY:
After the sbd_intr_o interrupt is asserted if the MAC TX is not in the LPI mode when you gate off the CSR clock, the events on the MAC transmitter do not get reported or updated in the CSR.
wait for the LPI exit indication from the PHY after which the MAC asserts the LPI exit interrupt on lpi_intr_o (synchronous to clk_rx_i). The lpi_intr_o interrupt is cleared when MAC_LPI_Control_Status Register is read.
