How do I setup a network interface


For the eagle interface do the following:

1. Make sure you have the eagle product installed.  If you have it installed
you will have the following files.

For NH4000 series:

	/usr/src/uts/machine/M88K/lib_eg
	/usr/src/uts/machine/M88K-RT/lib_eg
	/usr/src/uts/machine/hcxif/if_eg.h

For NH5000 series:

	/usr/src/uts/machine/NH5000/lib_eg
	/usr/src/uts/machine/NH5000-RT/lib_eg
	/usr/src/uts/machine/hcxif/if_eg.h


2. In the config file make sure the egintr line is uncommented.

	...
	driver  drXIw   cdev 54 vector drXIw_intr
	driver  eg              vector egintr    <---- eagle interrupt handler
	driver  cnd             vector cndintr
	driver  gs      cdev 57 vector vgintr
	....


3. Also, in the config file make sure the eagle device line is uncommented and
modified.

	...
	# device        eg0     at vba? csr 0xff0800    vector egintr
	....

To use a eagle board in the primary VME bus the lines would look like this.

	device        eg0     at vba0 csr 0xff0800    vector egintr

To use a eagle board in the secondary VME bus the lines would look like this.

	device        eg0     at vba1 csr 0xbfff0800    vector egintr


4. In /etc/rc uncomment and modify the ifconfig lines for the eagle device.

	...
		## The devices eg0, eg1, eg2, and eg3 are HVMEbus ethernet controllers.
		/usr/sbin/ifconfig eg0 down
	...
		## The devices eg0 ,eg1, eg2, and eg3 are HVMEbus ethernet controllers.
                /usr/sbin/ifconfig eg0 192.168.77.123 up -trailers netmask 255.255.255.0
	....


5. Build the appropriate device file in /dev.

	# cd /dev
	# ./MAKEDEV eg0


6. Rebuild and reinstall the new kernel.
