SGI Gigabit Ethernet Adapter For Windows NT

Jumbo Frames:
When checked, Jumbo Frames (up to 9,000 bytes) will be supported by the adapter.
This setting can reduce host CPU overhead and increase bandwidth when sending to
other devices that support Jumbo Frames. When attached to a switch that supports
Jumbo Frames, Jumbo Frames will be sent only between end-stations that have Giga-
bit Ethernet Adapters. When sending to standard Ethernet devices, the switch will
automatically fragment the Jumbo Frames traffic into standard Ethernet frames.
When unchecked (default), Jumbo Frames are disabled, and only standard Ethernet
frames will be sent. Use this setting when connecting to Gigabit Ethernet equipment
that does not support Jumbo Frames.
Rx Flow Control:
When checked (default), and link negotiation is enabled, the adapter will negotiate
802.3x receive flow control with the device at the other end of the link. If 802.3x flow
control is supported by the other device, it will be enabled.
When unchecked, or link negotiation is disabled, receive flow control is disabled.
Tx Flow Control:
When checked, and link negotiation is enabled, the adapter will negotiate 802.3x
transmit flow control with the device at the other end of the link. If 802.3x flow con-
trol is supported by the other device, it will be enabled.
When unchecked (default), or link negotiation is disabled, transmit flow control is
disabled.
