Andrew,
> Moving forward, how does your project use lwIP?
I am in simplest form, taking in SPI data and sending it out Ethernet. I can
get an SPI packet of 50 bytes approximately every 3ms though I am throughput
testing at 8ms currently.

No RTOS.

It is not called from an interrupt. I check while looping through main if any
packets have been added to a buffer and then send out that packet using
tcp_write().

Should be attached. I could use some help verifying I have it configured
correctly for my application with respect to the memory requirements at some
point too.
