求助与讨论：LAN91c111网卡芯片的调试 [对网卡or调试、有经验or感兴趣的朋友请进来！]我在Nios II7.2中跑Simple Socket Server软件例子，控制台提示：
。。。
Your Ethernet MAC address is 00:07:ed:ff:cb:c8
prepared 1 interface, initializing...
Created "Inet main" task (Prio: 2)
Created "clock tick" task (Prio: 3)
smsc91c111 Auto-negotiation: 100 Mbps, Full Duplex
SMSC ethernet Rev: 0x3392, ram: 8192
IP address of et1 : 0.0.0.0         //在调试思路I中变为192.168.1.234
DHCP timed out, going back to default IP address(es)

Simple Socket Server starting up
[sss_task] Simple Socket Server listening on port 30
Created "simple socket server" task (Prio: 4)

注意：网口的LINK和ACT指示灯正常，板子DIY的！
