The AMPE element includes number of optional and variable length fields and those cannot really be represented by a fixed struct ieee80211_ampe_ie. Remove the optional fields from the struct and build/parse these fields separately. This is also adding support for IGTKdata that was completely missing from the previous implementation. In addition, Key RSC for MGTK is now filled in and used when configuring the RX MGTK for a peer. Signed-off-by: Jouni Malinen <j@w1.fi>
