Enabling or Disabling Burst Count
This is a performance-tuning parameter. Enable sets single-word DMA burst
cycles. Disable sets eight-word burst cycles. Leave this parameter enabled except
when excessive TxUflo or RxOflo errors occur on the Ethernet ports of
• DSDE (5430 - Dual Synchronous, Dual Ethernet) link module
• DSE (5420 - Dual Synchronous, Single Ethernet) link module
Disable this parameter on the synchronous interface that is either running at a
lower clock speed or carrying lower-priority traffic. If disabling Burst Count on
only one DSDE interface does not eliminate errors on both Ethernet interfaces,
disable it on both synchronous interfaces.
