[realtek] re: dhcp problem with realtek 8139 clone

I too have a problem with dhcp, using an SMC 1211TX card (and the 8139too
code, since I need 2.4 kernel, and can't yet figure out how to use the 'real'
rtl8139.c with this kernel. Sorry, I'd much rather use the real thing)
My dhcp server is a old 2.2.17 linux box, across a 10 M ethernet (problem
also appear when I put a 10/100 switch in the way, so that the 1211 then uses
100 full duplex, not 10 half)
What I see on the server is that it receives the DHCPDISCOVER, and then sends
back the DHCPOFFER, but the 1211 doesn't see the replies (ifconfig gives no
packets rx, 4 tx for the 4 attempts before dhcpcd gives up).
If I manually set the address 'ifconfig eth0 X.Y.Z.W' to the address dhcp
will give out, and then restart the network, the 1211 then successfully
contacts the dhcp server, and gets a lease. (Yes, my dhcp uses fixed
During the successful case I get dhcpd: fallback_discard: Connection refused
errors twice. Sorry, not a DHCP expert.
It looks as if the 1211 is somehow not set to receive until it has an IP
address. After the first time, I can stop and start
/etc/rc.d/init.d/network, and it works fine.
Good ideas welcome
