Rx data frames notified through HTT_T2H_MSG_TYPE_RX_IND and HTT_T2H_MSG_TYPE_RX_FRAG_IND expect PN/TSC check to be done on host (mac80211) rather than firmware. Rebuild cipher header in every received data frames (that are notified through those HTT interfaces) from the rx_hdr_status tlv available in the rx descriptor of the first msdu. Skip setting RX_FLAG_IV_STRIPPED flag for the packets which requires mac80211 PN/TSC check support and set appropriate RX_FLAG for stripped crypto tail. Hw QCA988X, and QCA99X0 currently need the rebuilding of cipher header to perform PN/TSC check for replay attack.
