GigMAC PMC and PCI Board and Driver Users Manual
AccAllUni 0, 1 0
Setting this parameter to one instructs the
driver to receive all unicast frames
(sometimes useful in frame generator
testing). Do not enable for normal traffic.
ChipSelector 0, 1 0
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.
