If anyone has any objections, please let me know. ------------------ From: Yuchung Cheng [ 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") Signed-off-by: Yuchung Cheng Signed-off-by: Neal Cardwell Signed-off-by: David S.
