Subject: dnsdist: Reset the PP payload size when resetting the payload (restart)
X-Git-Tag: dnsdist-2.0.0-alpha2~20^2~2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=00322e987270f17d2dbcd66fbd710ff4d9f4e1f1;p=thirdparty%2Fpdns.git

dnsdist: Reset the PP payload size when resetting the payload (restart)

We fixed that for UDP backends in a previous commit, but this was still
an issue for TCP-based backends.
