3.19.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Malcolm Priestley <tvboxspy at gmail.com>

commit b23f14302e86628625ac3982a6d23e35888755f2 upstream.

Information for packet type is in ieee80211_tx_info

band IEEE80211_BAND_5GHZ for PK_TYPE_11A.

IEEE80211_TX_RC_USE_CTS_PROTECT via tx_rate flags selects PK_TYPE_11GB

This ensures that the packet is always the right type.
