|
|
* @details
|
|
* Indicate one or more of the following:
|
|
* - The tx frame already has a complete 802.11 header.
|
|
* Thus, skip 802.3/native-WiFi to 802.11 header encapsulation and
|
|
* A-MSDU aggregation.
|
|
* - The tx frame should not be aggregated (A-MPDU or A-MSDU)
|
|
* - The tx frame is already encrypted - don't attempt encryption.
|
|
* - The tx frame is a segment of a TCP jumbo frame.
|
|
* - This tx frame should not be unmapped and freed by the txrx layer
|
|
* after transmission, but instead given to a registered tx completion
|
|
* callback.
|
|
* More than one of these specification can apply, though typically
|
|
* only a single specification is applied to a tx frame.
|
|
* A compound specification can be created, as a bit-OR of these
|
|
* specifications.

* This UMAC SW can call this function to provide the tx data frames to
|
|
* the txrx layer.
|
|
* The UMAC SW can request a callback for these data frames after their
|
|
* transmission completes, by using the ol_txrx_data_tx_cb_set function
|
|
* to register a tx completion callback, and by specifying
|
|
* ol_tx_spec_no_free as the tx_spec arg when giving the frames to
|
|
* ol_tx_non_std.
|
|
* The MSDUs need to have the appropriate L2 header type (802.3 vs. 802.11),

|
* as specified by ol_cfg_frame_type().
