This patchset makes a couple of small corrections to the bonding driver
and introduces the ability to use an external state machine for mode
4 operation.

Changes in v2:
  . eliminate external_sm field in 802.3ad configuration 
    (rte_eth_bond_8023ad_conf).
  . stop bonding device before changing the periodic callback function.
    start again if needed.
  . remove unnecessary calls to valid_bonded_port_id().
  . do not check for NULL tx_ring.
  . return error in rte_eth_bond_8023ad_ext_slowtx() if packet is not LACP.
  . remove check for external sm configuration in periodic callback
  . check for valid LACPDU in test application's rx callback
  . add "Fixes:" tags

Eric Kinzie (4):
  bond mode 4: copy entire config structure
  bond mode 4: do not ignore multicast
  bond mode 4: allow external state machine
  bond mode 4: tests for external state machine

  Copy all needed fields from the mode8023ad_private structure in
  bond_mode_8023ad_conf_get().  This help ensure that a subsequent call
  to rte_eth_bond_8023ad_setup() is not passed uninitialized data that
  would result in either incorrect behavior or a failed sanity check.

Fixes: 46fb43683679 ("bond: add mode 4")

The bonding PMD in mode 4 puts all enslaved interfaces into promiscuous
mode in order to receive LACPDUs and must filter unwanted packets
after the traffic has been "collected".  Allow broadcast and multicast
through so that ARP and IPv6 neighbor discovery continue to work.

  Provide functions to allow an external 802.3ad state machine to transmit
  and recieve LACPDUs and to set the collection/distribution flags on
  slave interfaces.

You didn't add any of these to the version map.  Shared libraries wont have
these functions exported.  That also means it breaks the build:
