patch can fix the RX issue you're suffering from. Anyway, would you give it try the patch at the following URL? http://people.freebsd.org/~yongari/bce/bce.20100305.diff The patch was generated against CURRENT and you may see a message like "Disabling COAL_NOW timedout!" during interface up. You can ignore that message.

It's been running for about 1:23 on the patched driver. I'm still seeing the com_no_buffers increase:

[firewall2.jnb1] ~ # sysctl dev.bce |grep com_no_buffers dev.bce.0.com_no_buffers: 5642 dev.bce.1.com_no_buffers: 497 dev.bce.2.com_no_buffers: 6260612 dev.bce.3.com_no_buffers: 4871338

Interupt rate is down now, at about 3500 per second per interface.

Interestingly setting net.inet.ip.fastforwarding=0 reduces CPU consumption from 25% to 9% and less packet loss.
