Merge branch 'bonding-ns-validation-fixes' 

Hangbin Liu says:

====================
bonding: fix ns validation on backup slaves

The first patch fixed a ns validation issue on backup slaves. The second
patch re-format the bond option test and add a test lib file. The third
patch add the arp validate regression test for the kernel patch.

Here is the new bonding option test without the kernel fix:

]# ./bond_options.sh
