Subject: [PATCH RFC net-next 4/5] net: mvneta: move tso_build_hdr() into mvneta_tso_put_hdr()
Date: Mon, 03 Apr 2023 19:30:35 +0100 [thread overview]
Message-ID: <E1pjOwt-00Fml0-IJ@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <ZCsbJ4nG+So/n9qY@shell.armlinux.org.uk>
Move tso_build_hdr() into mvneta_tso_put_hdr() so that all the TSO
header building code is in one place.
