Subject: [PATCH v6 03/12] wcn36xx: Add ipv4 ARP offload support in suspend
Date: Sat,  5 Jun 2021 02:11:31 +0100	[thread overview]
Message-ID: <20210605011140.2004643-4-bryan.odonoghue@linaro.org> (raw)
In-Reply-To: <20210605011140.2004643-1-bryan.odonoghue@linaro.org>

Add ARP offload support. Firmware is capable of responding to ARP requests
for a single ipv4 address only.

Signed-off-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org>
