   4 Subject: [PATCH] proxyarp: fix compilation with Hotspot 2.0 disabled
   5
   6 The disable_dgaf config fiels is only available in case Hostapd is
   7 compiled with Hotspot 2.0 support, however Proxy-ARP does not depend on
   8 Hotspot 2.0.
   9
  10 Only add the code related to this config field when Hotspot 2.0 is
  11 enabled to fix compilation with the aformentioned preconditions.
