bond: fix mac assignment to slaves
Adding call to mac_address_slaves_update from the lsc handler when the first slave become active to propagate any mac changes made while devices are inactive Changed removing slave logic to use memmove instead of memcpy to move data within the same array, as this was corrupting the slave array. Adding unit test to cover failing assignment scenarios Test report: http://dpdk.org/ml/archives/dev/2014-December/009623.html Signed-off-by: Declan Doherty <declan.doherty@intel.com> Acked-by: Pawel Wodkowski <pawelx.wodkowski@intel.com> Tested-by: SunX Jiajia <sunx.jiajia@intel.com>
