- * lro_enable: 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

- * napi: This parameter used to enable/disable NAPI (polling Rx)
- * Possible values '1' for enable and '0' for disable. Default is '1'
- * ufo: This parameter used to enable/disable UDP Fragmentation Offload(UFO)
- * Possible values '1' for enable and '0' for disable. Default is '0'
- * vlan_tag_strip: This can be used to enable or disable vlan stripping.
- * Possible values '1' for enable , '0' for disable.
- * Default is '2' - which means disable in promisc mode
- * and enable in non-promiscuous mode.
- * multiq: This parameter used to enable/disable MULTIQUEUE support.

* fill_rx_buffers - Allocates the Rx side skbs
- * @ring_info: per ring structure
- * @from_card_up: If this is true, we will map the buffer to get

- * Else we will sync the already mapped buffer to give it to the card.
+ * @nic: device private variable
+ * @ring_no: ring number
* Description:
* The function allocates Rx side skbs and puts the physical
* address of these buffers into the RxD buffer pointers, so that the NIC
* can DMA the received frame into these locations.
- * The NIC supports 3 receive modes, viz
+ * The NIC supports 2 receive modes, viz
* 1. single buffer,
- * 2. three buffer and
- * 3. Five buffer modes.
+ * 2. Five buffer modes.
* Each mode defines how many fragments the received frame will be split
* up into by the NIC. The frame is split into L3 header, L4 Header,
* L4 payload in three buffer mode and in 5 buffer mode, L4 payload itself
* Return Value:
* SUCCESS on success or an appropriate -ve value on failure.
