If you mean the TCP_EVENT_XXX functions when you say "raw api" then yes, i
am using those callbacks. In TCP_EVENT_RECV i do something like;
if(pbuf)
{
//... do something
tcp_recved(pcb, pbuf->tot_len);
}
Both TCP_EVENT_SENT and TCP_EVENT_POLL return ERR_OK. The TCP fast timer
is invoked every 250ms and the slow timer every 500ms.

How are you using the lwIP interfaces? Are you using the raw API? I is
possible, using the raw API to generate dup acks if the "wrong"
functions are called at certain times.
