multiple ports simultaneously. This is accomplished using the bit port mask,
arg_PortMask, as the first argument of the function call. Any combination of valid
ports can be used.
The
in its third argument, arg_mode. Operational mode determines the following:
Interpretation of the arg_mode value
Speed auto-negotiation is not supported on IXB2850 board base interface ports. These
ports operate only in 1 GB full-duplex copper mode.
There is a bit in the mode parameter to specify either 4x8 or 1x32 SPI bus mode.
However, this bit is ignored by the driver for IXB2850 boards.
Using a separate
may want to apply different configurations for individual ports and all ports specified by
arg_PortMask are opened in the same operational mode. To change the operational
mode of a port once it is set, the application needs to close the port and then open it
again, specifying the new mode.
Ports can be opened by multiple applications for simultaneous use.
The application receives a handle that it must use for any future port reference. The
application provides a variable for the driver to store that handle.
It is important to initialize the variable to 0 before calling the
function. Otherwise, the driver may interpret a non-zero handle as a reference to
