X-Git-Tag: v2.6-dev8~26
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1809c33d6eb52beff14f9d02d811375619d3d347;p=thirdparty%2Fhaproxy.git

MINOR: quic: Mark packets as probing with old data

When probing retranmissions with old data are needed for the connection we
mark the packets as probing with old data to track them when acknowledged:
we do not resend frames with old data when lost.
