Subject: [PATCH net-next v3 RESEND 10/10] net: qualcomm: rmnet: Add support for GSO
Date: Sun, 7 Jan 2018 11:36:40 -0700 [thread overview]
Message-ID: <1515350200-29472-11-git-send-email-subashab@codeaurora.org> (raw)
In-Reply-To: <1515350200-29472-1-git-send-email-subashab@codeaurora.org>
Real devices may support scatter gather(SG), so enable SG on rmnet
devices to use GSO. GSO reduces CPU cycles by 20% for a rate of
146Mpbs for a single stream TCP connection.
