read

stmmac_dvr_probe : device pointer : platform data pointer : iobase memory address Description: this is the main probe function used to call the alloc_etherdev, allocate the priv structure.

stmmac_dvr_remove : net device pointer Description: this function resets the TX/RX processes, disables the MAC RX/TX changes the link status, releases the DMA descriptor rings.

stmmac_eee_init : private device pointer Description: If the EEE support has been enabled while configuring the driver, if the GMAC actually supports the EEE (from the HW cap reg) and the phy can also manage EEE, so enable the LPI state and start the timer to verify if the tx path can enter in LPI state.
