If you have having TX timeouts using polling, perhaps your system is so busy that its not running the cleanup routine in time, can you switch and run the interface in non-polled, in fact if possible using MSI??
I don't think the system is all that busy dual core 2.8Gz CPU... CPU mostly idle, and load is at 0.00. Here is the throughput on my busiest devices (lagg0 is em0 & em1):
