You can use dtrace to do this, but you likely need a lot of
information about how the stack itself works and how the driver was
written. It seems like a difficult and unlikely way to debug.
I wouldn't recommend starting there. Instead, I'd start with the
basics. What does "ifconfig -a" say? How about "netstat -ni"? Can
you ping the router if you use the "-n" flag? (If so, then the
problem is in name services, not the network card.)
Can you snoop the connection?

Again, debug information is essential. Anything in /var/adm/messages?
What does "ifconfig <interfacename> dhcp status" say?
Try setting up daemon.debug to log to a file (via /etc/syslog.conf),
then do this:
pkill dhcpagent
/sbin/dhcpagent -d 3 -v
ifconfig <interfacename> dhcp start
That should cause a great deal of debug information to be written to
the log file. If the problem is in DHCP itself, that should find it.
However, the symptoms you describe sound more basic to me: such as a
bad Ethernet cable or similar broken hardware. Are you sure you've
got the right port?

I'd always recommend the newest version.
