wireless scanning removes link address from cache manager

[Andrew Collins]

Here's the code snippit I'm using:

--- a/libnl/lib/route/link.c	Fri Aug 03 11:15:09 2012 -0600
+++ b/libnl/lib/route/link.c	Fri Aug 03 11:48:44 2012 -0600

 		goto errout;
 	}

+	/* Skip wireless events from legacy wireless drivers. */
+	if (tb[IFLA_WIRELESS] != NULL) {
+		err = NL_SKIP;
+		goto errout;
+	}
+
 	nla_strlcpy(link->l_name, tb[IFLA_IFNAME], IFNAMSIZ);

This works for my particular case, but doesn't seem entirely safe as
it requires all nl_cache_parse callers to understand NL_SKIP.
