+ * rx_ring_sz: This defines the number of receive blocks each ring can have.
+ *     This is also an array of size 8.
  * rx_ring_mode: This defines the operation mode of all 8 rings. The valid
  *		values are 1, 2 and 3.
  * tx_fifo_num: This defines the number of Tx FIFOs thats used int the driver.
  * tx_fifo_len: This too is an array of 8. Each element defines the number of
  * Tx descriptors that can be associated with each corresponding FIFO.
+ * intr_type: This defines the type of interrupt. The values can be 0(INTA),
+ *     1(MSI), 2(MSI_X). Default value is '0(INTA)'
+ * lro: Specifies whether to enable Large Receive Offload (LRO) or not.
+ *     Possible values '1' for enable '0' for disable. Default is '0'
+ * lro_max_pkts: This parameter defines maximum number of packets can be
+ *     aggregated as a single large packet
