This can be reproduced on any system with a nic that supports lro.  For
example:

$ sudo ethtool -k eth5 | grep large-receive-offload
large-receive-offload: on

$ sudo modprobe bonding
$ sudo ifenslave bond0 eth5
$ sudo brctl addbr br0
$ sudo brctl addif br0 bond0


without the patch, lro will still be on:

$ sudo ethtool -k eth5 | grep large-receive-offload
large-receive-offload: on

with the patch, lro will automatically get disabled when the bond is
added to the bridge:

$ sudo ethtool -k eth5 | grep large-receive-offload
large-receive-offload: off
