Subject: [PATCH 3/3] net: mhi: Increase the default MTU from 16K to 32K
Date: Tue, 6 Jun 2023 18:01:19 +0530 [thread overview]
Message-ID: <20230606123119.57499-4-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20230606123119.57499-1-manivannan.sadhasivam@linaro.org>
Most of the Qualcomm endpoint devices are supporting 32K MTU for the
UL (Uplink) and DL (Downlink) channels. So let's use the same value
in the MHI NET driver also. This gives almost 2x increase in the throughput
for the UL channel.
Below is the comparision:
iperf on the UL channel with 16K MTU:
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 353 MBytes 296 Mbits/sec
iperf on the UL channel with 32K MTU:
[ ID] Interval Transfer Bandwidth
[ 3] 0.0-10.0 sec 695 MBytes 583 Mbits/sec
