New firmware comes with new HTT protocol version. In 3.0 the separate mgmt tx command has been removed. All traffic is to be pushed through data tx (tx_frm) command with a twist - FW seems to not be able (yet?) to access tx fragment table so for manamgement frames frame pointer is passed directly.

The mgmt_rx event structure has been expanded. Since the structure header is expanded the payload (i.e. mgmt frame) is shifted by a few bytes. This needs to be taken into account in order to support both old and new firmware. This introduces a fw_features to keep track of any FW-related ABI/behaviour changes.

WEP encoding was not working properly for AP and IBSS mode.

In our Fuz testing, reference client corrupts the dest mac to "00:00:00:00:00:00" in the WPA2 handshake no 2. During driver init the sta_list entries mac addresses are by default "00:00:00:00:00:00".

Unify the PCI options location. By default the SoC PS option is disabled to boost the performance and due to poor stability on early HW revisions.

This fixes interrupt-related issue when no interfaces were running thus the device was considered powered down. The power_down() function isn't really powering down the device. It simply assumed it won't interrupt. This wasn't true in some cases and could lead to paging failures upon FW indication interrupt (i.e. FW crash) because some structures aren't allocated in that device state. One reason for that was that ar_pci->started wasn't reset. The other is interrupts should've been masked when teardown starts. The patch reorganized interrupt setup and makes sure ar_pci->started is reset accordingly.

If the device is removed and hotplug fails ioread32() will return 0xFFFFFFFF. In that case reading ringbuffer during device bringup led to out-of-bounds addressing of a ringbuffer array that in turn led to a paging failure. This could be reproduced by the following: * boot without acpi/prevent hotplug from working * insert and manually detect (pci rescan) the device * remove the device physically * load ath10k driver * kernel crashed Ringbuffer index reading is now protected by using an appropriate mask to prevent addressing an invalid array index.
