4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yuchung Cheng <redacted>
[ Upstream commit ce3cf4ec0305919fc69a972f6c2b2efd35d36abc ]
The v6 tcp stats scan do not provide TLP and ER timer information
correctly like the v4 version . This patch fixes that.
Fixes: 6ba8a3b19e76 ("tcp: Tail loss probe (TLP)")
Fixes: eed530b6c676 ("tcp: early retransmit")
