Thanks, applied with changes described below.

This seems to depend on libnl 3.1 or newer which is somewhat of an
unfortunate dependency to add since it breaks hostapd builds on most
existing platforms.. I added this as an optional build parameter instead
of replacement of the ioctl-based calls.

If the global parameter is fine (and why wouldn't it be?), it looks like
the ioctl-based interface can still be used with this in
full_dynamic_vlan_init():

-	vlan_set_name_type(VLAN_NAME_TYPE_PLUS_VID_NO_PAD);
+	vlan_set_name_type(hapd->conf->ssid.vlan_naming ==
+			   DYNAMIC_VLAN_NAMING_WITH_DEVICE ?
+			   VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PAD :
+			   VLAN_NAME_TYPE_PLUS_VID_NO_PAD);


If that is not enough, adding CONFIG_VLAN_NETLINK=y into hostapd/.config
will replace the kernel API to netlink (with the cost of having to have
a suitable libnl version available).
