This parameter is a bit mask that
specifi es which speed and duplex
settings the board advertises. When
this parameter is used, the Speed
and Duplex parameters must not be
specifi ed.
This parameter is supported only on
adapters using copper connections.
NOTE: Refer to the Speed and
Duplex section of this readme for
more information on the AutoNeg
parameter.
Duplex
0-2 (0=auto-ne-
gotiate, 1=half,
2=full)
0
Defi nes the direction in which data
is allowed to fl ow. Can be either one
or two-directional. If both Duplex and
the link partner are set to auto-ne-
gotiate, the board auto-detects the
correct duplex. If the link partner is
forced (either full or half), Duplex
defaults to half-duplex.
This parameter is supported only on
adapters using copper connections.
