+Subject: [PATCH] tracepath: restore the MTU probing behaviour since release
+ 20071127
+
+Since 81d0f03 (tracepath: fix IP{V6,}_PMTUDISC_DO values), tracepath
+shows the PMTU for a target only at the first hop but not the hop where
+MTU is reduced, if that data has been cached in kernel FIB by previous
+probing attempts.
+
+IP_PMTUDISC_PROBE instructs the kernel to set the Don't Fragment flag
+while bypassing PMTU checks. Usage of IP_PMTUDISC_PROBE in tracepath was
+introduced in 37bd60c and mentioned in the release note of 20071127
+(1d83610) as a feature.
+
+As previously identified in 81d0f03 (appeared in release 20190709), the
+definition of these options became incorrect during a copy refactoring in
+d3028f1 (in release 20100418). The value for IP_PMTUDISC_PROBE continued
+to be used until 81d0f03 when the correct definition of IP_PMTUDISC_DO was
+adopted, thus causing a regression.
+
+This commit resotres the previous behaviour by adopting IP_PMTUDISC_PROBE.
+
+Fixes: d3028f1, 81d0f03
