You can't bridge LACP - it doesn't even make sense. LACP bundles must
be between adjacent devices. Moreover, LACPDUs are destined for a
bridge-management address that is prohibited from being bridged by
802.1D.
What are you trying to accomplish? If you want to transparently
bridge with LACP channels, you should terminate the LACP bundles on
the Linux box and bridge the bundles:
eth0 \ / eth2
bond0 ----- br0 ---- bond1
eth1 / \ eth3
And then cable eth0/eth1 to one device and eth2/eth3 to the other.
