Module Name:    src
Committed By:   jonathan

Modified Files:
        src/sys/dev/pci: if_bge.c

Log Message:
Add a table of Rx interrupt-threshold register values for mitigating
Rx interrupts, functions to post a request for new table entries, and
code to apply pending Rx-interrupt control values at the next hardware
interrupt.

As used in a third-party proprietary tree since at least March 2003.
As discussed on tech-kern/tech-net in January 2004 (in the context of
NetBSD for packet capture, bpf, and FreeBSD-sylte IFF_POLL), and as
posted to tech-net for comments in mid-March 2004.

Still missing sysctl or other knobs to acutally change the config-time
values, due to my ignorance of any accepted per-device sysctl namespace.
