RE: [lwip-users] tcp_write() errors on snd_queuelen

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.
