From f23c3d3175e55ebac81d6e29f1c1415491a78d60 Mon Sep 17 00:00:00 2001

Subject: [PATCH] rt2x00: Detect cypher type during RX (rt2800pci)
Use UDF field in WCID entry to pass the cipher type
to the RXWI fields. This will allow keeping track of
the number of frames received with a particular cipher type
which is exported through debugfs.
