- * See the file COPYING in this distribution for more information.
- *
- * Credits:
- * Jeff Garzik : For pointing out the improper error condition
- * check in the s2io_xmit routine and also some
- * issues in the Tx watch dog function. Also for
- * patiently answering all those innumerable
- * questions regaring the 2.6 porting issues.
- * Stephen Hemminger : Providing proper 2.6 porting mechanism for some
- * macros available only in 2.6 Kernel.
- * Francois Romieu : For pointing out all code part that were
- * deprecated and also styling related comments.
- * Grant Grundler : For helping me get rid of some Architecture
- * dependent code.
- * Christopher Hellwig : Some more 2.6 specific issues in the driver.
- *
- * The module loadable parameters that are supported by the driver and a brief
- * explanation of all the variables.
- *
- * rx_ring_num : This can be used to program the number of receive rings used
- * in the driver.
- * 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.
- * 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),
- * 2(MSI_X). Default value is '2(MSI_X)'
- * lro_max_pkts: This parameter defines maximum number of packets can be
- * aggregated as a single large packet
- * 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.
- * Possible values '1' for enable and '0' for disable. Default is '0'
