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. 

 

 
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, 
 

 
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 
 

 
 

 
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.
