Subject: [PATCH v5 10/12] wcn36xx: Add Host suspend indication support
Date: Tue, 1 Jun 2021 16:09:59 +0100 [thread overview]
Message-ID: <20210601151001.1450540-11-bryan.odonoghue@linaro.org> (raw)
In-Reply-To: <20210601151001.1450540-1-bryan.odonoghue@linaro.org>
In order to activate ipv4 ARP offload, ipv6 NS offload and firmware GTK
offload we need to send a unidirectional indication from host to wcn
indicating a transition to suspend.
Once done, firmware will respond to ARP broadcasts, ipv6 NS lookups and
perform GTK rekeys without waking the host.
