NAME

  sys_attrs_tu - tu subsystem attributes

DESCRIPTION

  This reference page lists and	describes attributes for the tu	(tu) kernel
  subsystem. This subsystem is used by the  10/100 Mb/s	Ethernet adapters.

  Refer	to the sys_attrs(5) reference page for an introduction to the topic
  of kernel subsystem attributes.



  StoreAndForward
      A	value that enables (1) or disables (0) the store and forward opera-
      tion on the DC21x4x Ethernet chip.

      When enabled, the	DC21x4x	chip will copy the entire packet to the	chip
      prior to transmit.  When disabled, the driver will attempt dynamic set-
      ting of the size of the chip's transmit FIFO.  Set this parameter	to 1
      (enabled)	if you do not want the driver to dynamically adjust the
      DC21x4x chip's transmit FIFO size.

      Default value: 0 (disabled)



  delay_6694F
      A	value that enables (1) or disables (0) the 400 millisecond delay
      associated with operating	with the 6694F part on the DE500-BA.  This
      parameter	only affects operation on DE500-BA equivalent equipment.

      Do not modify the	default	setting	for this attribute unless instructed
      to do so by support personnel or patch kit documentation.

      Default value: 1 (enabled)
