Hello,
The patch below we already use since 2006.
We had problems with the TCP/IP stack directly after booting because it
already received packets before being initialized completely.
Here our CVS log:
move
splx(s);
from line 682 to line 739
so that tcp/ip stack has started up before the ethernet driver is released
(else the not-ready stack will already receive packets)
Do you agree this is a valid patch?
