0044 Driver for the Efficient Networks ENI155p series and SMC ATM
0045 Power155 155 Mbps ATM adapters. Both, the versions with 512KB and
0046 2MB on-board RAM (Efficient calls them "C" and "S", respectively),
0047 and the FPGA and the ASIC Tonga versions of the board are supported.
0048 The driver works with MMF (-MF or ...F) and UTP-5 (-U5 or ...D)

0058 Extended debugging records various events and displays that list
0059 when an inconsistency is detected. This mechanism is faster than
0060 generally using printks, but still has some impact on performance.

0065 bool "Fine-tune burst settings"
0066 depends on ATM_ENI
0067 help
0068 In order to obtain good throughput, the ENI NIC can transfer
0069 multiple words of data per PCI bus access cycle. Such a multi-word
0070 transfer is called a burst.
0071
0072 The default settings for the burst sizes are suitable for most PCI
0073 chipsets. However, in some cases, large bursts may overrun buffers
0074 in the PCI chipset and cause data corruption. In such cases, large
0075 bursts must be disabled and only (slower) small bursts can be used.
0076 The burst sizes can be set independently in the send (TX) and
0077 receive (RX) direction.
0078
0079 Note that enabling many different burst sizes in the same direction
0080 may increase the cost of setting up a transfer such that the
0081 resulting throughput is lower than when using only the largest
0082 available burst size.
0083
0084 Also, sometimes larger bursts lead to lower throughput, e.g. on an
0085 Intel 440FX board, a drop from 135 Mbps to 103 Mbps was observed
0086 when going from 8W to 16W bursts.
