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:

      Hangbin Liu authored 
      This patch add bonding arp validate tests with mode active backup,
monitor arp_ip_target and ns_ip6_target. It also checks mii_status
to make sure all slaves are UP.

      selftests: bonding: re-format bond option tests · 481b56e0
      Hangbin Liu authored 
      To improve the testing process for bond options, A new bond topology lib
is added to our testing setup. The current option_prio.sh file will be
renamed to bond_options.sh so that all bonding options can be tested here.
Specifically, for priority testing, we will run all tests using modes
1, 5, and 6. These changes will help us streamline the testing process
and ensure that our bond options are rigorously evaluated.

      bonding: fix ns validation on backup slaves · 4598380f
      Hangbin Liu authored 
      When arp_validate is set to 2, 3, or 6, validation is performed for
backup slaves as well. As stated in the bond documentation, validation
involves checking the broadcast ARP request sent out via the active
slave. This helps determine which slaves are more likely to function in
the event of an active slave failure.

However, when the target is an IPv6 address, the NS message sent from
the active interface is not checked on backup slaves. Additionally,
based on the bond_arp_rcv() rule b, we must reverse the saddr and daddr
when checking the NS message.

Note that when checking the NS message, the destination address is a
multicast address. Therefore, we must convert the target address to
solicited multicast in the bond_get_targets_ip6() function.

Prior to the fix, the backup slaves had a mii status of "down", but
after the fix, all of the slaves' mii status was updated to "UP".

      niu: Fix missing unwind goto in niu_alloc_channels() · 8ce07be7
      Harshit Mogalapalli authored 
      Smatch reports: drivers/net/ethernet/sun/niu.c:4525
	niu_alloc_channels() warn: missing unwind goto?

If niu_rbr_fill() fails, then we are directly returning 'err' without
freeing the channels.

Fix this by changing direct return to a goto 'out_err'.
