There's a macro tcp_sndbuf(pcb) that you can use to find out the current
fill level of the queue. You may also need to pay attention to
tcp_sndqueuelen(pcb) which is used to prevent lots of small packets
using up lots of resources and so can prevent a tcp_write() from
succeeding. Have a look in the source at how these two are used to give
an idea of the tests you need to make.
