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