From 84a65fd6a3fca2bd960f5c26fa95d035b1195d87 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Sun, 17 Nov 2013 20:23:51 +0200 Subject: [PATCH] Extend GCMP test vectors to include both MPDUs IEEE Std 802.11ad-2012 includes two test vectors for GCMP. Verify both of those and also verify that the results match the values in the standard instead of just verifying that decrypted frame matches original.
