Subject: Get index of address from netlink when network interface aliases are active

Steps:
1. create some network aliases. ifconfig command returns list
eth0
eth0:0
eth0:1
lo
2. create AF_NETLINK socket and send RTM_GETADDR message to it
3. received events:
RTM_NEWADDR
  IFA_LABEL : "lo"
  ifa_index     : 0
RTM_NEWADDR
  IFA_LABEL : "eth0"
  ifa_index     : 1
RTM_NEWADDR
  IFA_LABEL : "eth0:0"
  ifa_index     : 1
RTM_NEWADDR
  IFA_LABEL : "eth0:1"
  ifa_index     : 1
4. delete network alias "eth0:1", than "eth0:0"
5. received events
RTM_DELADDR
  IFA_LABEL : "eth0:1"
  ifa_index     : 1
RTM_DELADDR
  IFA_LABEL : "eth0:0"
  ifa_index     : 1

Is there a way to get right address index? I want to make one-to-one
correspondence between address and data pointer. Without right address
index I cant use simple dynamic array. I have to perform event's
address hashing and use hash table or tree.

Thank you.
