What does 'data abort' mean ?
Is something printed on the console ?
Do you see some type of packet that indicates an abort in a protocol ?

You have only posted a small part of networkconfig.h so it is difficult to say
if there is a problem.
Can you ping the target once the network is connected ?
Can you ping with large sizes, eg 30k ?

This depends on the demands of your system. The only correct priority is the
one that works for you and your application.

These should be enough to allow testing. This how-ever depends on the amount
of data in the system and if TCP or UDP is being used.
