From 269084f748524fa1a3fb8eb530eb70f77e7c3e4a Mon Sep 17 00:00:00 2001 From: Menglong Dong Date: Thu, 3 Oct 2024 16:22:31 +0800 Subject: net: tcp: refresh tcp_mstamp for compressed ack in timer For now, we refresh the tcp_mstamp for delayed acks and keepalives, but not for the compressed ack in tcp_compressed_ack_kick(). I have not found out the effact of the tcp_mstamp when sending ack, but we can still refresh it for the compressed ack to keep consistent.
