Hi Alexander,
I'm running yum 3.0.6 on my 4.7 boxes. I have plans to create dbus
client emitting messages via xml-rpc to Cacti. See

So finally got it working, r8169 is a piece of crap, at least at 2.6.18
kernel :o). Got e1000 cards (Intel PRO/1000 MT), working like a charm.
Seems to me that via-rhine is the very same as r8169.

Just for the record:
1. dhcp on bonding adapter with 802.3ad is not going to work, use static one
2. modes 5,6 work both static and dhpc
3. mode 5 works pretty well across multiple switch units
4. mode 6 does not
5. 802.3ad reacts the most slowly, you have to set lacp_rate=3Dfast and
set switch LACP timeout to the lowest one.
6. mode 5 setting primary=3Deth0 - once eth0 is up, traffic goes to eth0
back, without primary remains on the last adapter to run
7. and do not forget to use ETHTOOLS_OPT=3D"speed 1000" on physical adapters
8. test done against DLINK DGS-3110-24 (modes 5,6,802.3ad) and one
unmanaged switch (modes 5,6)

OK, I'm gonna test it with use_carrier. I have been playing with
arp_ip_target and miimon without luck.

>From documentation: 'It is critical that either the miimon or
arp_interval and arp_ip_target parameters be specified, otherwise
serious network degradation will occur during link failures.  Very few
devices do not support at least miimon, so there is really no reason not
to use it.'

And as to MII, ethertool on all netcard but old 3com shows no support
for MII. And as to bonging I want to get 802.3ad working.
Thanks,
DH
