44 Driver for the Efficient Networks ENI155p series and SMC ATM
45 Power155 155 Mbps ATM adapters. Both, the versions with 512KB and
46 2MB on-board RAM (Efficient calls them "C" and "S", respectively),
47 and the FPGA and the ASIC Tonga versions of the board are supported.
48 The driver works with MMF (-MF or ...F) and UTP-5 (-U5 or ...D)

58 Extended debugging records various events and displays that list

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

a7f7f624 67 help
1da177e4
LT
68 In order to obtain good throughput, the ENI NIC can transfer
69 multiple words of data per PCI bus access cycle. Such a multi-word
70 transfer is called a burst.
71
72 The default settings for the burst sizes are suitable for most PCI
73 chipsets. However, in some cases, large bursts may overrun buffers
74 in the PCI chipset and cause data corruption. In such cases, large
75 bursts must be disabled and only (slower) small bursts can be used.
76 The burst sizes can be set independently in the send (TX) and
77 receive (RX) direction.
78
79 Note that enabling many different burst sizes in the same direction
80 may increase the cost of setting up a transfer such that the
81 resulting throughput is lower than when using only the largest
82 available burst size.
83
84 Also, sometimes larger bursts lead to lower throughput, e.g. on an
85 Intel 440FX board, a drop from 135 Mbps to 103 Mbps was observed
86 when going from 8W to 16W bursts.
