You should probably initialize type, state, and mtu here.

Done.

[dmichael (off chromium), 2012/03/02 16:43:12]

If the caller passes a count less than the total available, don't you want to
return to them the number of addresses you have? As-is, I think you'll return
the number they passed you, and they don't have a way of knowing that there are
other addresses to get.

[Sergey Ulanov, 2012/03/02 18:43:03]

Done. Thanks for catching this!

[dmichael (off chromium), 2012/03/02 16:43:12]

This enum doesn't seem right here, since we're not talking about a
NetworkListType. I think just using 0 directly makes more sense here?

[Sergey Ulanov, 2012/03/02 18:43:03]

Done.
