Noted on this, I will update you through this thread.

However is there any possibility of the following:

What I mean here is, for the two interfaces:

one IRQ for bce0 Rx
one IRQ for bce0 Tx
one IRQ for bce1 Rx
one IRQ for bce1 Tx


Thanks,

Won

There was a ***major*** bce(4) cleanup that just happened.  Your 7.0 box
will not have these changes.  Please upgrade your box to RELENG_7
(a.k.a. 7.1-PRERELEASE), csup'd recently (today preferably), and try
your tests again:
