to receive all unicast frames (sometimes useful in
frame generator testing). Do not enable for
normal traffic.
ChipSelector
0, 1 1
Sets the chipset selector (0=National, 1=Intel).
Default is National chipset.
FrameGenSize
60-MaxMtuSize 1500
Sets the frame generator frame size for testing
end-to-end or loopback.
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
