 * ol_txrx_ops - (pointers to) the functions used for tx and rx
 * data xfer
 *
 * There are two portions of these txrx operations.
 * The rx portion is filled in by OSIF SW before calling
 * ol_txrx_osif_vdev_register; inside the ol_txrx_osif_vdev_register
 * the txrx SW stores a copy of these rx function pointers, to use
 * as it delivers rx data frames to the OSIF SW.
 * The tx portion is filled in by the txrx SW inside
 * ol_txrx_osif_vdev_register; when the function call returns,
 * the OSIF SW stores a copy of these tx functions to use as it
 * delivers tx data frames to the txrx SW.
 *
 * @tx.std -  the tx function pointer for standard data
 * frames This function pointer is set by the txrx SW
 * perform host-side transmit operations based on
 * whether a HL or LL host/target interface is in use.
 * @tx.flow_control_cb - the transmit flow control
 * function that is registered by the
 * OSIF which is called from txrx to
 * indicate whether the transmit OS
 * queues should be paused/resumed
 * @rx.rx - the OS shim rx function to deliver rx data
 * frames to. This can have different values for
 * different virtual devices, e.g. so one virtual
 * device's OS shim directly hands rx frames to the OS,
 * but another virtual device's OS shim filters out P2P
 * messages before sending the rx frames to the OS. The
 * netbufs delivered to the osif_rx function are in the
 * format specified by the OS to use for tx and rx
 * frames (either 802.3 or native WiFi). In case RX Threads are enabled, pkts
 * are given to the thread, instead of the stack via this pointer.
 * @rx.stack - function to give packets to the stack. Differs from @rx.rx.
 * In case RX Threads are enabled, this pointer holds the callback to give
 * packets to the stack.
 * @rx.wai_check - the tx function pointer for WAPI frames
 * @rx.mon - the OS shim rx monitor function to deliver
 * monitor data to Though in practice, it is probable
 * that the same function will be used for delivering
 * rx monitor data for all virtual devices, in theory
 * each different virtual device can have a different
 * OS shim function for accepting rx monitor data. The
 * netbufs delivered to the osif_rx_mon function are in
 * 802.11 format.  Each netbuf holds a 802.11 MPDU, not
 * an 802.11 MSDU. Depending on compile-time
 * configuration, each netbuf may also have a
 * monitor-mode encapsulation header such as a radiotap
 * header added before the MPDU contents.
 * @rx.std - the OS shim rx function to deliver rx data
 * @proxy_arp - proxy arp function pointer - specified by
 * OS shim, stored by txrx
 * @get_key - function pointer to get key of the peer with
 * specific key index
