Hi Sven!  My apologies on taking so long to reply.

I haven't been able to reproduce your issue yet, but with your description it sounds that the issue could be related to the X710 hardware LLDP engine consuming the LLDP packets.  To disable the hardware engine, user the following command on each of the ports that you're using in the bond:
ethtool --set-priv-flags <interface name> disable-fw-lldp on

Then the LLDP packets that the bonding modules relies on will be forwarded by the hardware to the OS network stack.

I hope you have a great weekend!
Dave
