From: Mattias Nissler <mattias.nissler@xxxxxx>
Add a flag to struct txdata_entry_desc that specifies whether an ack for the
frame is to be expected. Use this flag to set the ACK bit in the tx descriptor.
Previously, the ACK bit could be set incorrectly on CTS-to-self frames, so they
caused retries and were reported to be failed in the txdone handlers.
