This doesn't happen for me on my local testing network with RELENG_6
built from October 14 sources.

These boxes generally throw about 350mbit in/out of TCP between each other.
I've recently upgraded one to RELENG_7 to test so I can't provide a
dmesg+interrupt count for it. Note that under load the interrupts are
around 8000/sec for em0 but I haven't run the tests for a few days and
thus the "rate" figure for em0 is a bit misleading.

wendy# vmstat -i
interrupt total rate
irq1: atkbd0 76 0
irq6: fdc0 1 0
irq15: ata1 46 0
irq17: em0 fwohci0 1503419876 1866
irq19: atapci1 766603 0
irq20: ohci0 ohci+ 0 0
cpu0: timer 1611280255 2000
