Subject: Statistics and yet one fix for 3C509

I have done another fix for 3C509 driver. It gives no
overruns on input now and finally it's possible to measure
its throughput.

I have tested it with FTP connection between my machine (Packard
Bell 486DX2/66 w/512K cache) and ICL minicomputer that is able
to transfer upto 1.1Mbytes per second by transferring a 10M file.
Here are results (looking from my machine):

ftp> get file /dev/null

	about 850 K/s
	systat gives about 85% of interrupts for
	processor's load

ftp> get file

	about 640 Kbytes/s

ftp> put file

	about 670 Kbytes/s

So I think 3c509 isn't the best card for servers.

Driver lies at wcarchive.cdrom.com/pub/FreeBSD/incoming/3c509c.*
