[lwip-users] Send out TCP packet asap?

[Chen]

Hi there,

I use lwip_send (....0), along with FreeRTOS on AVR32, to send out TCP
packets

Each time I call, I present 200 bytes to lwip. From Wireshark, I can see
the packets size alternating between 200 and 1400 bytes with more idle
time right before the 1400-byte packet

Is there a flag I can set so that lwip sends out the packet (200 bytes)
if the output queque is empty, without trying to packaging the data to
make it more efficient?

Thanks for your reply!
