+The length field of wext data (iw_point.data) is 16 bits. The largest
+value is thus 65535. During the attempts to increase buffer size the
+buffer starts at 4096 and is doubled after each failure to fill. From the
+time this length reaches 65536 it is effectively zero. We thus loose all
+potential space from 32768 to 65535.

+This problem is clear when scanning in a RF dense environment.
