FUNCTIONALITY TESTING

When the driver is loaded into the system via `insmod' it probes the PCI bus to locate all DP83820 devices, and creates control structures for each. The driver logs a couple of messages available in `/var/log/messages' for each device with information about its PCI geographic location, IRQ, IO address, and some basic debug information (addresses of some important structures).

All the devices on the PCI bus can be listed by,

#cat /proc/pci

#cat /proc/interrupts

IRQ and IO address information from this can be correlated with the information displayed by the driver in `/var/log/messages'

When the TCP/IP stack is initialized, it opens all configured ethernet devices, and initializes them for use. At this time, the driver will perform auto negotiation and log information about the link status. The driver can then be tested by running ping, telnet, ftp, NFS etc.

Suggested basic verifications to be run

lsmod	# lists loaded drivers
ifconfig	# lists configured network interfaces
dmUtil -s eth[n]	# prints low-level driver statistics for device
ping <ip addr>	# ping to remote station to verify

ADDITIONAL VERIFICATION AND PERFORMANCE TESTING

Verification and performance testing can be done using the Linux "uxBlaster" and "uxBlastee" test programs found on OEM developer kit CD. The 'dmUtil' utility program also found on the CD can be used to obtain valuable information used for debug and integration verification.

dmUtil -s eth0 # displays low-level driver statistics
