[lwip-users] How to properly send packets of size greater than snd_buf? |

How am I supposed to send packets of size greater than the pcb's snd_buf?
Right now my snd_buf is 8192 bytes, but the packets I am sending can be
~150kb. I know that one of the suggested methods is to return control to
main, and then use the tcp_poll callback function to finish sending the data
once the snd_buf has cleared, but this method is way too slow and I cannot
afford to wait like this. I need to force the whole packet to send right
away (or at least as fast as the receive can receive).
I have tried using tcp_nagle_disable() and then tcp_output() but this does
not work. The snd_buf still does not clear out.
Any suggestions? I'm stumped at the moment.
