Hi Kieran,

the 36 pbufs with 256 bytes each and 1200 byte MSS did not work ;-)

Is there a recommendation of the relation between pbuf size and MSS? I did not find anything about this is the documentation ...

First of all, 6 pbufs seems not to be very much, and as i understood

MSS.
    

I wonder if your driver can handle that case correctly?  It has to know
to split the received packet across pbufs.  A naive driver might ignore
pbuf chains (on send as well as receive).
