Subject: [PATCH RFC v1 02/15] mvneta: add XDP frame size to driver
Date: Tue, 17 Mar 2020 18:29:17 +0100 [thread overview]
Message-ID: <158446615781.702578.17438189744745816482.stgit@firesoul> (raw)
In-Reply-To: <158446612466.702578.2795159620575737080.stgit@firesoul>
This marvell driver mvneta uses PAGE_SIZE frames, which makes it
really easy to convert. It also only updated rxq and now frame_sz
once per NAPI call.
