configure LACP in linux box with ex switch

  The current physical topology as below:

  ge-0/0/11  <========> linux eth2  (direct link)

  ge-0/0/13  <========> linux eth3  (direct link)

  ae0 is aggragated using ge-0/0/11 and ge-0/0/13 in the EX side

  bond0 is aggrated using eth2 and eth3 in linux box with fixed ip address 1.1.1.99.
