      Fresh install of Xenserver 7.0 in Supermicro SYS-2028TR-HTR. It has two dual-port Intel NICs, one of 1 GB and another one with 10 GB ports.

      Description

      I've installed XS 7.0, with no error. After configuring a LACP bond on the two 10 GB ports, the Link Status of the bond is "Disconnected". The ports of the switch are configured too.

      _# /usr/bin/ovs-appctl bond/show bond0
      ---- bond0 ----
      bond_mode: balance-slb
      bond may use recirculation: no, Recirc-ID : -1
      bond-hash-basis: 0
      updelay: 31000 ms
      downdelay: 200 ms
      next rebalance: 4858 ms
      lacp_status: negotiated
      active slave mac: 00:00:00:00:00:00(none)

      slave eth2: disabled
      may_enable: false

      slave eth3: disabled
      may_enable: false_

      If I configure an Active-Active or Active-Passive bond, the link is up.

      If I install XS 6.5, LACP works.

      I think the problem is with the driver from Intel, as I've been able to reproduce this issue in a FreeBSD 10.3 .
