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?
