Except for your call to tcp_write(). You need to sort this out with TI: either
a) you must call tcp_write() from the same interrupt context or
b) the ethernet driver interrupt must not call into lwIP or
c) you need to disable the ethernet interrupt while calling any lwIP function 
from your main application.
