Subject: [PATCH 5/9] net: efi-snp: Allocate own receive buffer
Date: Mon, 19 Sep 2022 10:01:29 +0200 [thread overview]
Message-ID: <20220919080133.877651-6-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20220919080133.877651-1-s.hauer@pengutronix.de>
Use a driver private buffer as network receive buffer rather than the
globally allocated ones which will be removed soon.
