      This is our setup when using bonding interface

      We have vlan sub interface on bonding interface, it's on the same bridge of vhost interface, 

      ~$ vppctl show bridge 4 detail
  ID   Index   Learning   U-Forwrd   UU-Flood   Flooding   ARP-Term     BVI-Intf
  4      1        on         on         on         on         off          N/A

           Interface           Index  SHG  BVI  TxFlood        VLAN-Tag-Rewrite
      BondEthernet0.1099         4     0    -      *                 pop-1
     VirtualEthernet0/0/0        5     0    -      *                 none
     VirtualEthernet0/0/1        6     0    -      *                 none

      The vhost interface has mac address fa:16:3e:0c:63:28, however in the l2fib, the bonding interface always own it, this caused l2 connectivity drops on the vhost interface

       ~$ vppctl show l2fib verbose

      system and vpp version
