The secret appears to be
pciconf -l -v | grep -i express
device = 'BCM5750A1 NetXtreme Gigabit Ethernet PCI Express'
This bge(4) Broadcom chip had problems in 6.0 but works well in 6.2.
The critical part for my application is not getting the maximum
number of packets per second, but in not dropping any, and
getting them acked rapidly. The closed source "black box" on the
other end of the wire has a buggy network stack, a *way* too small
transmit buffer, and generates data in real time that I have only
one chance to capture.
The remaining problem is that other device drivers can lock it out.
