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. 87 88config ATM_ENI_BURST_TX_16W 89 bool "Enable 16W TX bursts (discouraged)" 90 depends on ATM_ENI_TUNE_BURST 91 help 92 Burst sixteen words at once in the send direction.
