Driver for the Efficient Networks ENI155p series and SMC ATM |

Power155 155 Mbps ATM adapters. Both, the versions with 512KB and |
|
2MB on-board RAM (Efficient calls them "C" and "S", respectively), |
|
and the FPGA and the ASIC Tonga versions of the board are supported. |
|
The driver works with MMF (-MF or ...F) and UTP-5 (-U5 or ...D) |

config ATM_ENI_TUNE_BURST |
|
bool "Fine-tune burst settings" |
|
depends on ATM_ENI |
|
help |
|
In order to obtain good throughput, the ENI NIC can transfer |
|
multiple words of data per PCI bus access cycle. Such a multi-word |
|
transfer is called a burst. |
|
|
|
The default settings for the burst sizes are suitable for most PCI |
|
chipsets. However, in some cases, large bursts may overrun buffers |
|
in the PCI chipset and cause data corruption. In such cases, large |
|
bursts must be disabled and only (slower) small bursts can be used. |
|
The burst sizes can be set independently in the send (TX) and |
|
receive (RX) direction. |
|
|
|
Note that enabling many different burst sizes in the same direction |
|
may increase the cost of setting up a transfer such that the |
|
resulting throughput is lower than when using only the largest |
|
available burst size. |
|
|
|
Also, sometimes larger bursts lead to lower throughput, e.g. on an |
|
Intel 440FX board, a drop from 135 Mbps to 103 Mbps was observed |
|
when going from 8W to 16W bursts. |
