Subject: QUIC: use client max_ack_delay when computing pto timeout.
X-Git-Tag: release-1.25.0~4^2~448
X-Git-Url: http://git.kaiwu.me/postgresql/log/contrib/postgres_fdw/static/gitweb.js?a=commitdiff_plain;h=6f9efd423ed225bf1cf25f173aaf99cbedc57e3f;p=nginx.git

QUIC: use client max_ack_delay when computing pto timeout.

Previously, server max_ack_delay was used which is wrong.

Also, level check is simplified.
