From 97e0496d056726ab46e7e977315f2ab847b34209 Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Mon, 12 Sep 2011 13:47:34 +0300 Subject: [PATCH] ath6kl: add firmware capabilities support The new firmware format includes capability bits which make it possible to check what features the firmware supports. Add infrastructure to read the capabilities. For now it only provides ATH6KL_FW_CAPABILITY_HOST_P2P which is not even used anywhere yet, but that will be added later.
