This sounds like a driver bug. Are you using the stm32 demo code? It has this problem. The problem is that the interrupts are being lost but the packets are still there in the hw rx buffer. You need random rx packets to trigger new interrupts. I posted some code recently that fixes this issue.
All:
A strange problem happen after device running some days.
After power on, PING response is fast. But after running some days, ping response becomes lower and timeout sometimes.
I configure ICMP checksum by hardware. Anyone has same problem ?
