Subject: net: hns3: Increase the default depth of bucket for TM shaper
Patch-mainline: v4.16-rc1
Git-commit: 3a7d59588ab282f105a2a82a38f0fa4a2c9c5032
References: bsc#1104353 FATE#326415

Burstiness of a flow is determined by the depth of a bucket, When the
upper rate of shaper is large, the current depth of a bucket is not
enough.

The default upper rate of shaper is 100G, so increase the depth of
a bucket according to UM.
