annotate src/core/ngx_output_chain.c @ 8285:0697294f79a4 quic
QUIC: removed redundant "app" flag from ngx_quic_close_frame_t.
The flag was introduced to create type-aware CONNECTION_CLOSE frames,
and now is replaced with frame type information, directly accessible.
Notably, this fixes type logging for received frames in b3d9e57d0f62.
