bond: send gratuitous arp when the active slave went down in active-backup mode
- Modify the API send_ip6_na and send_ip4_garp to take sw_if_index instead of vnet_hw_interface_t and add call to build_ethernet_rewrite to support subinterface/vlan - Add code to bonding driver to send an event to bond_process when the first interface becomes active or when the active interface is down - Create a bond_process to walk the interface and the corresponding subinterfaces to send garp/ip6_na when an event is received. - Minor cleanup in bonding/node.c Note: dpdk bonding driver does not send garp/ip6_na for subinterfaces. There is no attempt to fix it here. But the infra is now done and should be easy to add the support. Change-Id: If3ecc4cd0fb3051330f7fa11ca0dab3e18557ce1 Signed-off-by: Steven <sluong@cisco.com>
