annotate src/event/quic/ngx_event_quic_ack.h @ 8822:ad046179eb91 quic
QUIC: handle EAGAIN properly on UDP sockets.
Previously, the error was ignored leading to unnecessary retransmits.
Now, unsent frames are returned into output queue, state is reset, and
timer is started for the next send attempt.
