annotate src/event/ngx_event_openssl.h @ 8512:6e1c88f82280 quic
QUIC: changed ctx->largest_ack initial value to type maximum.
In particular, this prevents declaring packet number 0 as lost if
there aren't yet any acknowledgements in this packet number space.
For example, only Initial packets were acknowledged in handshake.
