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