I might suggest, however, that the combination of Broadcom NICs, bonded,
and the Cisco device is the cause of the problem.

If you switch to a single NIC (for testing) with no bonding, does the
problem go away or does it get worse?

It seems that you may need to do some system tuning to get your system
to handle the high packet rates you have - it's likely the pps, not the
bps, which is the source of the problem.

What Broadcom driver is being used?
