[lwip-users] snd_queuelen underflow frustration

I'm trying to port lwIP 1.4.1 and httpserver_raw to a PIC32MZ. No RTOS. After a web client establishes a TCP connection, it sends a GET to httpserver_raw/lwIP, it returns with two large packets (1514 bytes), then the client sends an ACK. It's at that point an underflow occurs in tcp_in.c line
