Subject: [PATCH 2/8] qtnfmac: cleanup and fixes preparing AP_VLAN support
Date: Tue, 20 Jun 2017 22:55:11 +0300 [thread overview]
Message-ID: <20170620195517.18373-3-sergey.matyukevich.os@quantenna.com> (raw)
In-Reply-To: <20170620195517.18373-1-sergey.matyukevich.os@quantenna.com>
This patch implements various cleanups and fixes aimed to
simplify adding AP_VLAN support to qtnfmac driver:
- Remove unused flag field from qlink_intf_info
- Add interface type to qlink_cmd_change_sta
- Modify qtnf_cmd_send_change_sta: add interface type to command
- Fix handling of iftype mask reported by firmware:
Firmware sends supported interface type rather than mask. As a result,
types field of ieee80211_iface_limit structure may end up having
multiple iftype bits set. This leads to WARN_ON from
wiphy_verify_combinations.
