Driver for the Efficient Networks ENI155p series and SMC ATM

|
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)

help
|
Extended debugging records various events and displays that list

generally using printks, but still has some impact on performance.

itself. Enable this ONLY if you suspect problems with the driver.

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.
