I'm running 11.10 on an Intel SR2625URLXR system with an Intel S5520UR
motherboard and an Intel E1G42ET Dual Port Server Adapter. I'm getting
dropped packets on a bonded interface:
$ ifconfig -a

eth2 and eth3 are on the Intel E1G42ET Dual Port Server Adapter.
The switch these two ports are connected to is a Summit 400-48t, with
the ports they're connected to configured for LACP:
Summit400-48t:1 # show configuration
...
configure sharing address-based ip-source
...
enable sharing 17 grouping 17,21 dynamic
...

1. If eth2 and eth3, which make up bond0, show no dropped packets, why
am I seeing dropped packets on bond0? I've tested the network
cables and they're ok. I've tested the two ports on the Intel
E1G42ET Dual Port Server Adapter and they're ok. I've tested the
ports on the switch and they're ok. I'm only seeing dropped packets
when I enable bonding.
2. Why isn't the bond0 interface "up"?
