>Release:        FreeBSD 2.1-STABLE i386
>Environment:

	3Com Elink-III 3c509 ethernet card tested with many motherboards
	The all files are dated OCT. 21, and floppy is dated OCT. 23.

>Description:

	The 3c509 ethernet card has been found, but not configured to
	given host id:
# ifconfig -a
lp0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1500
ep0: flags=863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX> mtu 1500
        ether 00:00:24:34:12:d7
lo0: flags=8009<UP,LOOPBACK,MULTICAST> mtu 16384
        inet 127.0.0.1 netmask 0xff000000 
sl0: flags=c010<POINTOPOINT,LINK2,MULTICAST> mtu 552
tun0: flags=8010<POINTOPOINT,MULTICAST> mtu 1500

	Also, after manually configuring ep0 correctly, it won't go further
	than one hop. i.e., if the machine is on 128.3.123 net, then, it
	won't see 128.3.124 net even though it can see the router and all
	other hosts on the 128.3.123 net.

>How-To-Repeat:

	See Description

>Fix:
	
	The installer works fine. I rebuild the kernel, the problem is
	still in. So, the bug is in some modified code for either the
	3Com driver or in the network driver.
