I just compiled and installed a kernel with the new nfe(4) driver and
DEVICE_POLLING enabled. Below are the results of some scp(1) transfers:

stock nfe(4):	2.5 MB/sec
new nfe(4):	3.7 MB/sec
polling:	4.1 MB/sec

The driver is a lot better than the stock nfe(4). Are there any plans to
add the new nfe(4) to the sourcetree?
