This patch is for adding IPv6 NS/NA monitor support for bonding. I
posted a RFC patch before[1]. And the iproute2 patch is here [2].
Based on Nikolay's suggestion on RFC patch, I did
1. define BOND_MAX_ND_TARGETS as BOND_MAX_ARP_TARGETS
2. adjust for reverse xmas tree ordering of local variables
3. remove bond_do_ns_validate()
4. add extra field for bond_opt_value
5. set IS_ENABLED(CONFIG_IPV6) for IPv6 codes
---
This patch add bond IPv6 NS/NA monitor support. A new option
ns_ip6_target is added, which is similar with arp_ip_target.
The IPv6 NS/NA monitor will take effect when there is a valid IPv6
address. Both ARP monitor and NS monitor will working at the same time.
A new extra storage field is added to struct bond_opt_value for IPv6 support.
Function bond_handle_vlan() is split from bond_arp_send() for both
IPv4/IPv6 usage.
To alloc NS message and send out. ndisc_ns_create() and ndisc_send_skb()
are exported.

bonding: add extra field for bond_opt_value
bonding: add new parameter ns_targets
bonding: add new option ns_ip6_target
