[Bug 1041070] Re: 802.3ad bond interface have show high RX dropped packets

[Steve Boyle]

I'm seeing the same thing.  Yes, my switch is configured for 802.3ad.
The bond comes up but drops 2pps consistently.  I see the vast majority
of the drops on the bond0 interface, the underlying eth0 and eth1
interfaces each show much less loss than bond0.
