Thank you,

I'll check the bit 31 in nb_buff address when I will test again the board.

About freeing the packet:

I derived my send function from arp_send() or similar ones. I have no knowledge of proper usage of those free and lock calls.

In the Opencore driver the raw_send function is NULL when I don't define the sync mode, so pkt_send is used. In sync mode it's the opposite: pkt_send is defined as NULL and a raw_send is used.

In all case I always had TSE driver using pkt_send.

Clearly, the pkt_send functions differ from one driver to the other.
