RE: [lwip-users] Remote tcp connection with TAPIF interface

[jean-louis . gilbert]

Hi all,

I have some problems with TFTP communications...

When the host has to make an ARP_REQUEST (and ARP_REPLY) to update its ARP
table, i noticed that the first UDP packet isn't sent to the network...
hence, for the TFTP application the WRQ or RRQ request never reach the
remote host.... and the TFTP application isn't set in one or another mode,
and so does't take into account the following DATA packets (which reach the
remote host !)...

I notice that at the end of udp_send(...) function, there is a
"pbuf_free(p)", which remove this pbuf. Is "q", the new allocated pbuf (a
copy), really taken into account in the FIFO in order to be sent another
times (by the thread) ?

Thanks for you help...
regards
