packet drop with intel gigabit / marwell gigabit

[Michael Vince]

I use netperf which is a pure network traffic tester I also just use 
basic 'ab/apache' tests which would also test HD/IO if getting large files.
For the 'em' driver I have seen some posts/cvs commit updates to the 
driver saying it now works better without polling then with polling. I 
think this is in -stable but it might just be in current. I haven't done 
any testing for a while.
