<At the netif input stage you have 60 bytes, which will I think include the 
<ethernet header (14 bytes).  That leaves 46 bytes of IP packet, which is the 
<value that the pbuf ends up as, so that calculation is correct.  However the IP 
<header says there should be 52 bytes (or more in your subsequent post).  So my 
<guess is that your netif driver is not passing up all the data.  Perhaps you 
<have pbufs of length 60 and the driver is supposed to chain many of them 
<together with all the data, but it isn't doing this correctly?


There was indeed a failure in the netif input stage.
My Buffers where cycling not in a correct way.
