There may be some interrupt handling changes coming, but at least for
the moment you need to increase the storm threshold, or set it to 0 to
disable it.

Intel can only support a finite set of hardware, it is NOT a matter of it
being some "Intel" part, its
a matter of some SFPs that are out there DO NOT WORK, so engineering here
was able to
delimit, validate, and thus certify a specific set of SFPs, the software
check is there to make
sure that you

Your nmbclusters is very low, you list it twice so I'm assuming the second
value is
what it ends up being, 32K :(
I would set it to:
kern.ipc.nmbclusters=262144
Also, I thought you were using the current driver, but now it looks like you
are
using something fairly old, use my latest code which
If you go to FreeBSD 8 you will get the improved stack code, and the RX/TX
queue pairs
will be pinned to cpus. It should improve performance.
Make sure you have enough mbuf memory allocated, try increasing the
descriptors.
