Duplicate receives with multiple reads



Hello,

I have a problem with duplicate packets being received by my read complete routine.
I have a receive ring size of 8 and I perform 8 asynchronous reads before I start packet reception. When I get a read complete, I process the packet and perform another read to keep my buffer ring full of armed reads.
Every so often, I get completely duplicate packets received, which I first noticed using ping.


This does not happen when I have only one outstanding read instead of 8.

Has anyone else experienced this or knows what might be causing this?

Thanks very much for any pointers.

Cheers,
Gerald
