Subject: [PATCH net-next 4/5] net: mvneta: move tso_build_hdr() into mvneta_tso_put_hdr()
Date: Wed, 10 May 2023 11:15:58 +0100	[thread overview]
Message-ID: <E1pwgrW-001XE4-DB@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <ZFtuhJOC03qpASt2@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.
