How interesting. I upgraded from igb 2.1.0-k2 to 2.4.12, rebooted, and 
without changing anything else, DRBD sync performance has dropped through 
the floor; it's less than a fifth of what it was previously. All rx off, 
tx off, gro off, mtu=9000, etc. With iperf, I get 1.98 Gb/sec.

Whether or not it is actually working correctly I will not know until 
tomorrow; it claims to be another 26 hours before the volume (1.8 TB) has 
finished syncing. Too slow to be useful in any event.
