Subject: [PATCH V2 net-next 05/12] net: hns3: fix for shaper not setting when TC num changes

From: Yunsheng Lin <linyunsheng@...wei.com>

Shaper setting does not change currently, when TC num changes,
which may cause shaper parameter not setting problem.

This patch fixes it by setting the shaper parameter when TC num
changes.
