Subject: [PATCH] qcacmn: Add Support for ACTION_CATEGORY_FST

Currently, mgmt_txrx_get_action_frm_subtype does not handle
ACTION_CATEGORY_FST. In case action_category is
ACTION_CATEGORY_FST, mgmt_txrx_get_action_frm_subtype
returns MGMT_FRM_UNSPECIFIED due to default handling. Function
tgt_mgmt_txrx_rx_frame_handler returns QDF_STATUS_E_FAILURE
on receiving MGMT_FRM_UNSPECIFIED frame type and drops mgmt
frames.

Fix is to add support for ACTION_CATEGORY_FST in
mgmt_txrx_get_action_frm_subtype to avoid drop of FST mgmt
frames. Add new management frames
MGMT_ACTION_FST_SETUP_REQ, MGMT_ACTION_FST_SETUP_RSP,
MGMT_ACTION_FST_TEAR_DOWN, MGMT_ACTION_FST_ACK_REQ,
MGMT_ACTION_FST_ACK_RSP, MGMT_ACTION_FST_ON_CHANNEL_TUNNEL.
Add handling for ACTION_CATEGORY_FST in
mgmt_txrx_get_action_frm_subtype, Find fst frame subtype and
return fst frame subtype from mgmt_get_fst_action_subtype
instead of returning MGMT_FRM_UNSPECIFIED in case FST
action_category is received.
