dev.ix.0.queueX.interrupt_rate

[Slawa Olhovchenkov]

I have '82599ES 10-Gigabit SFI/SFP+ Network Connection' and see
strange:

# sysctl dev.ix.0 | grep interrupt_rate
dev.ix.0.queue7.interrupt_rate: 500000
dev.ix.0.queue6.interrupt_rate: 500000
dev.ix.0.queue5.interrupt_rate: 31250
dev.ix.0.queue4.interrupt_rate: 31250
dev.ix.0.queue3.interrupt_rate: 31250
dev.ix.0.queue2.interrupt_rate: 500000
dev.ix.0.queue1.interrupt_rate: 500000
dev.ix.0.queue0.interrupt_rate: 500000

Last -stable, no tuning. Is this normal?
