Bug Description
[Impact]
iwlist scan can search the available wifi APs, but can't get connected.
On new Intel platforms like ApolloLake, legacy interrupt mechanism
(INTx) is not supported, so WLAN modules are not working because
interrupts are missing.
The affected and listed platforms are
Dell Inspiron 24-3460
Dell Inspiron 14-3473
Dell Inspiron 3472
Dell Inspiron 3576
Dell Vostro 3262
Dell Vostro 15-3572
Dell Vostro 3578
[Fix]
Qualcomm provided a MSI patch for ath9k, and it fixes the issue.
[Test Case]
Tested on the machines mentioned above, and they all work well.
[Regression Potential]
There shouldn't be any regression potential. These are newly enabled machines and quirks are applied based on DMI_PRODUCT_NAME to only use MSI on such machines.
