    Retry setting mac address on new OVS port 10 times
    
    We've seen several times in the gate an OVS add port call
    succeed and then have the mac address set fail to find it
    seconds later. The vswitch log frequently shows that it
    returns milliseconds later. Until we get to the bottom of
    it, we should just retry several times before giving up
    and raising.

Title:
  test_connection_from_diff_address_scope intermittent "Cannot find
  device" errors

Status in neutron:
  Fix Released

Bug description:
  Example TRACE:
  http://logs.openstack.org/58/360858/4/check/gate-neutron-dsvm-functional/3fb0ba3/console.html#_2016-08-30_23_25_18_854125

  It looks like OVSDB adds an internal OVS port, then when we try to set
  the MTU, the linux network stack cannot find the device.

  I'm under the impression that https://review.openstack.org/#/c/344859/
  was supposed to solve this class of issues.
