HDCP Compliance Test Known Issues for Release 2.9.0

Test 3C-I-06
--------------

Fixed a bug where we were not creating a bad downstream Bksv value quickly enough.
Sometimes, when the repeater DUT would get the upstream authentication, it would read the downstream Bksv value before we could create the bad one and have it read that. Having read a proper downstream Bksv value, the DUT would finish authentication with the downstream device and assert its upstream KSV FIFO bit and would hence get a FAIL result on the test. The creation of this bad Bksv value has been moved much earlier in the process, well before the TE authenticates on the upstream interface of the DUT so as to minimize/eliminate this race condition.

Test 3C-II-01
---------------

In this test, we do not handle the case where a DUT authenticates more than once on its downstream interface. We are expecting just a single authentication. If the DUT authenticates more than once, each write of a new An and Aksv pair will reset the KSV FIFO ready bit and additionally, a new Mo' is calculated. Thus, we need to recalculate V' and set the KSV FIFO ready bit.
