From aefb4f06db3a837b7e93f8088c1d4882aa9a5041 Mon Sep 17 00:00:00 2001 From: Chengwen Feng Date: Wed, 3 Feb 2021 20:23:50 +0800 Subject: [PATCH 036/189] net/hns3: constrain TM peak rate User could config Port or TC's peak rate by TM ops, but hardware does not support peak rate which lower than 1Mbps. So we constraint TM peak rate must be at least 1Mbps.
