In that case I believe you've hard coded the number of queues, check
/boot/loader.conf
for references to this.
Yes, that's true:
% cat /boot/loader.conf
debug.acpi.max_tasks="128"
if_lagg_load="YES"
kern.ipc.nmbclusters="131072"
hw.igb.num_queues="1"
I am wondering why I have turned this on..
My box has raidz2 ZFS box with SSD mirrored log..
We find that large numbers of queues causes high interrupt issues
however at a guess you did this to enable the machine to boot with
all nics due to lack of auto mbuf tuning in 9.x.
I'd go with ~2 queues per nic.
