Previous implementation was incorrectly using MGTK also as the IGTK and doing this regardless of whether PMF was enabled. IGTK needs to be a independent key and this commit does that at the local TX side. The current AMPE element construction and parsing is quite broken, so this does not get add the IGTKdata field there. Signed-off-by: Jouni Malinen <j@w1.fi>
