Hello,

What is the current state of support for multithreaded TCP processing in
CURRENT? If a NIC supports multiple queues, will they be used
automatically or net.isr.numthreads needs to be increased?

I have this situation on a machine with an igb card:

irq256: igb0:que 0                103573         11
irq257: igb0:que 1                 10094          1
irq258: igb0:que 2                 18231          2
irq259: igb0:que 3                 18186          2

This looks like the first queue is used ~~ 10x more often than the
others. Is this a problem?
