在调试GD32F407和RTL8201网卡的时候发现 网卡能正常接收电脑的数据 但是不能发送任何数据出去,大家有遇见过吗?
pbuf_header: old 2000cf6a new 2000cf7e (-20)
udp_input: received datagram of length 58
udp (192.168.57.255, 137) <-- (192.168.57.1, 137)
pbuf_free(2000cf4c)
pbuf_free: deallocating 2000cf4c
pbuf_alloc(length=92)
pbuf_alloc: allocated pbuf 2000cf4c
pbuf_alloc(length=92) == 2000cf4c
ethernet_input: dest:ff:ff:ff:ff:ff:ff, src:50:7b:9d:04:25:72, type:800

src:50:7b:9d:04:25:72 这个是电脑的网卡

月入3000的是反美的。收入3万是亲美的。收入30万是移民美国的。收入300万是取得绿卡后回国,教唆那些3000来反美的!
