Hi Michael,

We try boning two broadcom 5709 nics with active-backup mode, we try to
down/up one of the nics, I found some ping packets loss as below:
# ifdown eth0 
# ifup eth0  <-- no pkg loss 
# ifdown eth1 
# ifup eth1  <-- 2 pkg loss 
# ifdown eth0 
# ifup eth0  <-- 10 pkg loss 
# ifdown eth1 
# ifup eth1 <-- no pkg loss 
# ifdown eth0 
# ifup eth0  <-- 10 pkg loss 

module bond parameter are:
"mode=1 miimon=100 primary=eth0 downdelay=100 updelay=100"

we have tried the latest driver(2.0.8c) of broadcom and Redhat el5.5
official driver(2.0.2), result are same.

I checked and debugged the driver found it caused by take long time(~3s)
to bring up the device. here are link state when call if up:
# ifdown eth0 
# ifup eth0   
#ip -o link | grep eth0 
2: eth0: <BROADCAST,MULTICAST,SLAVE,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master bond0 qlen 1000\    link/ether 00:26:55:4f:1f:18 brd ff:ff:ff:ff:ff:ff 
# ifdown eth1 
# ifup eth1   
#ip -o link | grep eth1 
3: eth1: <NO-CARRIER,BROADCAST,MULTICAST,SLAVE,UP> mtu 1500 qdisc pfifo_fast master bond0 qlen 1000\    link/ether 00:26:55:4f:1f:18 brd ff:ff:ff:ff:ff:ff 
# ifdown eth0 
# ifup eth0   
#ip -o link | grep eth0 
2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,SLAVE,UP> mtu 1500 qdisc pfifo_fast master bond0 qlen 1000\    link/ether 00:26:55:4f:1f:18 brd ff:ff:ff:ff:ff:ff 
# ifdown eth1 
# ifup eth1   
#ip -o link | grep eth1 
3: eth1: <NO-CARRIER,BROADCAST,MULTICAST,SLAVE,UP> mtu 1500 qdisc pfifo_fast master bond0 qlen 1000\    link/ether 00:26:55:4f:1f:18 brd ff:ff:ff:ff:ff:ff 
# ifdown eth0 
# ifup eth0 
#ip -o link | grep eth0 
2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,SLAVE,UP> mtu 1500 qdisc pfifo_fast master bond0 qlen 1000\    link/ether 00:26:55:4f:1f:18 brd ff:ff:ff:ff:ff:ff 

So, the question is how long alway will take when bring up the interface?
3 seconds as expection or no? if not, is that a firmware issure or driver
issue?

Thanks,
Joe
