Previously, GSO emission was explicitely disabled on backend side. This is not true since the following patch, thus GSO can be used, for example when transfering large POST requests to a HTTP/3 backend. commit e064e5d46171d32097a84b8f84ccc510a5c211db MINOR: quic: duplicate GSO unsupp status from listener to conn However, GSO on the backend side may cause crash when handling EIO. In this case, GSO must be completely disabled. Previously, this was performed by flagging listener instance. In backend side, this would cause a crash as listener is NULL. This patch fixes it by supporting GSO disable flag for servers. Thus, in qc_send_ppkts(), EIO can be converted either to a listener or server flag depending on the quic_conn proxy side. On backend side, server instance is retrieved via <qc.conn.target>. This is enough to guarantee that server is not deleted. This does not need to be backported.
