Subject: [PATCH 4.16 019/161] cxgb4: fix offset in collecting TX rate limit info

4.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Rahul Lakkireddy <rahul.lakkireddy@...lsio.com>

[ Upstream commit d775f26b295a0a303f7a73d7da46e04296484fe7 ]

Correct the indirect register offsets in collecting TX rate limit info
in UP CIM logs.

Also, T5 doesn't support these indirect register offsets, so remove
them from collection logic.
