Subject: BUG/MINOR: do not crash on QMux reception of BLOCKED frames
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=63febbace73c712fad31d13a53b24268190bed58;p=thirdparty%2Fhaproxy.git

BUG/MINOR: do not crash on QMux reception of BLOCKED frames

Add QUIC BLOCKED frames in the list of supported types in
qstrm_parse_frm(). Nothing is really implemented for them as for QUIC,
but this prevents a crash when receiving one of them via QMux.

No need to backport.
