Subject: Re: [PATCH 2/6] ath9k: add a quirk to set use_msi automatically

Ath9k is an old driver for old chips, and they work fine with legacy INTx.
But some new platforms are using it, so I think we should list those
new platforms which blocks INTx in the driver.

BTW, new chips use ath10k driver.
