Not seeing any changes to core dumps, or crashes after updating the
bce(4) interface on these Dell R410s.  IPMI was a definite false hope.
No changes noted after I modified the ipmi_attach code.

stable/7 works just fine and stable/9 fails with "NMI" erros on the
console very badly.  It fails so badly that it won't come into service
at all.  I've reverted stable/9 back to august of 2012 with no changes.

It sort of looks like r236216 is causing severe issues with my
configuration.  The Dell R410 has a 3rd ethernet interface for the BMC
only, not sure if that is meaningful in this context.

The 3rd interface is *not* visible from the o/s and is dedicated to the
BMC interface.

Doing more testing at this time to validate.



FWIW, I have an R210 with a BCM5716 running 9.1 RELEASE without
any problems. I have customized the driver a bit. Try turning off the
"features" and running it raw without any checksum or tso gobbledygook.
