[Xen-API] XCP 1.6 build 61809c bonding issue - lost connection on ProLiant BL465c G7 with Emulex NC551i dual-port 10 Gb CNA and HP VC Flex-10 Enet Module

I use this hardware configuration:

ProLiant BL465c G7 with embedded Emulex NC551i dual-port 10 Gb Converged Network Adapter
Two HP VirtualConnect Flex-10 Enet Module
Cisco C2960G

All firmwares are in current versions. Emulex NC551i using FW version 4.1.450.7 corresponding with be2net Emulex OneConnect 10Gbps NIC Driver 4.1.450.7 in XCP kernel.

I set two NICs to bond0:

eth0 is in the network on the first HP VC Flex-10 with uplink thru port X3 connected to C2960G eth1 is in the network on the second HP VC Flex-10 with uplink thru port X3 connected to C2960G

This is easiest setup for redundant connections over two HP VC Flex-10 verified as correct by HP support without any hardware problems.

After switching off the first HP VC Flex-10, all traffic is automatically send thru second HP VC Flex-10 - this is OK. After switching on the first HP VC Flex-10, communication is interrupted forever - this is BAD.
The problem can be solved only after reboot XCP.

I'm creating bond by using this command:

xe bond-create network-uuid=uuid_bond_network pif-uuids=uuid_eth0,uuid_eth1

States of NIC correspond with output of:

ovs-appctl bond/show bond0

I would appreciate any advice.

Thank you
