qc_notify_send() is used to wake up the MUX layer for sending. This function first ensures that all sending condition are met to avoid to wake up the MUX for unnecessarily. One of this condition is to check if there is room in the congestion window. However, when probe packets must be sent due to a PTO expiration, RFC 9002 explicitely mentions that the congestion window must be ignored which was not the case prior to this patch. This commit fixes this by first setting <pto_probe> of 01RTT packet space before invoking qc_notify_send(). This ensures that congestion window won't be checked anymore to wake up the MUX layer until probing packets are sent. This commit replaces the following one which was not sufficient : commit e25fce03ebe3307bc104d1f81356108e271d2bc3 BUG/MINOR: quic: Dysfunctional 01RTT packet number space probing This should be backported up to 2.7.
