Hi Team,
I have been trying to bring up the 88W9064 wifi card in the LS1046ARDB board.
The Linux version used was 4.1.35, that comes bundled along with the QorIQ SDK 2.0 - 1703.
Experimented with all the versions of the driver sources available in the Product page.
There were some issues w.r.t compiling the .ko file, but eventually fixed all issues.
All the generated modules stops at the same error while performing `insmod` of the module.
On further debugging, traced to the exception handler that causes the issue. Since that exception is raised from the HW, the respective handling halts the Tx and Rx path.
Even after exception, the wireless interfaces are created, but those were not working.
The exception handler: `wlSC5MSIX_r7`
Adding the snippet of the logs below, which shows the exception error.
```
