Subject: [PATCH net] bus: mhi: Add mru_default for Foxconn SDX55
Date: Sat, 15 Jan 2022 18:39:12 +0800 [thread overview]
Message-ID: <20220115103912.3775-1-slark_xiao@163.com> (raw)
For default mechanism, product would use default MRU 3500 if
they didn't define it. But for Foxconn SDX55, there is a known
issue which MRU 3500 would lead to data connection lost.
So we align it with Qualcomm default MRU settings.
