Datagram re-order in msquic lib (receiver side)

[ashish284]

I am prototyping a use case where data is sent from msquic server to msquic client in datagram mode. I am observing that the datagram is getting reordered on the receiver side. On further inspection through wireshark (with encryption disabled), I found out that on the sender side and on the receiver side the datagram was received in order, it seems like reorder is happening in msquic lib on the receiver side. Is this expected? Any config to get data in order (as on wireshark on receiver side data was in proper order).

Datagrams are indicated directly inline from the connection's receive packet processing code. You can see QuicDatagramProcessFrame is where we process the frame from the QUIC packet and then it is indicated directly to the app.
