Similar problems happens to me.
Target is a PPC8xx custom one with a derived SCC driver.
(the "old" stack is working fine)

DHCP at boot time is not working.
its seems i have the same behaviour described in
http://sources.redhat.com/ml/ecos-discuss/2002-01/msg00418.html
(Re: DHCP server xid)

Testing the ping_test with a static IP address
results in 

PING server 10.16.2.20
64 bytes from 10.16.2.20: icmp_seq=0, time=0ms
recvfrom: Operation timed out
64 bytes from 10.16.2.20: icmp_seq=2, time=0ms
recvfrom: Operation timed out
64 bytes from 10.16.2.20: icmp_seq=4, time=0ms
 :
 .

ethereal shows the echo requests and replys.
it seems an ICMP echo reply with a payload of
(N mod 4 != 0) is not handled correctly.
( 64 is working, 65, 66, 67 isnt working, 68 is working ....).

BTW: a TCP connect() is returning -1. :-/
starting to track it down...

any ideas?, regards Christoph
