The devices with PCI device ID 0x34F0 are part of the SoC and can be
combined with some different external RF modules. The configuration
for these devices should reflect that, but are currently mixed up. To
avoid confusion with discrete devices, add part of the firmware to be
used and the official name of the device to the cfg structs.
This is least reorganization possible (without messing things even
more) that could be done as a bugfix for this SoC. Further
reorganization of this code will be done separately.

Probe responses were sent to the multicast station while

This has no negative effect since the frame was still

The parameter that indicated whether the LQ command should be sent
as sync or async was removed, causing the LQ command to be sent as
sync from interrupt context (e.g. from the RX path). This resulted
in a kernel warning: "scheduling while atomic" and failing to send
the LQ command, which ultimately leads to a queue hang.
Fix it by adding back the required parameter to send the command as
sync only when it is allowed.

When we receive TX response, we may release a few packets
due to a hole that was closed in the transmission window.
However, if that frame failed, we will mark all the released

Instead, mark all the following packets as success, with the

When the NIC is disconnected, we just can't do anything
besides seeking for help from the bus driver. Dumping the
device's memory is not necessary and just bloats the logs
with unusable data. Moreover, asking mac80211 to restart
the hardware is also useless. Bypass all this.
Also, use the STATUS_TRANS_DEAD status bit instead of a
bool inside the transport layer. The advantage of this is
that now, the transport and the op_mode can know what is the
situation and bypass the useless recovery steps mentioned
above.

A probe response built by a P2P GO should contain:

2. If the corresponding probe request had P2P IE, then
need to add P2P IE with NOA attributes.
However, the NOA attributes and the updated channel switch
counter are known only to the FW. The solution is that FW
will send a notification with the relevant probe response
