We have a mwifiex patch depends on it. Part of the patch looks this:

+               if (hdr->len > 3 &&
+                   ext_cap->ext_capab[3] & WLAN_EXT_CAPA4_INTERWORKING_ENABLED)
+                       priv->hs2_enabled = 1;
+               else
+                       priv->hs2_enabled = 0;

If this bit is enabled we will drop the GARP frames received. This is required for WFA Hotspot2.0.

Thanks,
Bing
