problems sending packets on solaris 10

I am having the exact same problems that "seph" reported last month:
a) DHCPD 4.0.0 reports a bizarre looking 32 byte MAC address on startup
b) Clients never receive an offer.I am running on top of Solaris Express snv_70b
*** # /apps/dhcp/sbin/dhcpd -d -cf /apps/dhcp/etc/dhcpd.conf -4  e1000g0
*** Internet Systems Consortium DHCP Server 4.0.0
*** ...
*** Listening on DLPI/e1000g0/00:31:00:00:00:03:00:00:00:00:00:00:00:04:00:00/
*** Sending on   DLPI/e1000g0/00:31:00:00:00:03:00:00:00:00:00:00:00:04:00:00/
*** Sending on   Socket/fallback/fallback-net
*** DHCPDISCOVER from 00:15:c5:39:7f:12 via e1000g0
*** DHCPOFFER on to 00:15:c5:39:7f:12 (LX318747) via e1000g0
Note: the dhcpd daemon logs the first DHCPDISCOVER that comes in from the network.
It appears to generate a DHCPOFFER but the offer never reaches the client.
When snooping on the interface, snoop sees the incomming DHCPDISCOVER but not the DHCPOFFER.
The dhcpd daemon only logs the "first" DHCPDISCOVER it receives.
It won't log any subsequent DHCPDISCOVERS.
>Version 3.1.0 does not appear to have this problem. And it displays

>much more correct.
