Subject: QUIC: handling packets with send time equal to lost send time.
X-Git-Tag: release-1.25.0~4^2~595
X-Git-Url: http://git.kaiwu.me/postgresql/log/contrib/postgres_fdw/static/gitweb.js?a=commitdiff_plain;h=3bf7b02e6eccb6e51161693d887fccac18afaf38;p=nginx.git

QUIC: handling packets with send time equal to lost send time.

Previously, such packets weren't handled as the resulting zero remaining time
prevented setting the loss detection timer, which, instead, could be disarmed.
For implementation details, see quic-recovery draft 29, appendix A.10.
