Add quic_dgram new structure to store information about datagrams received by the sock I/O handler (quic_sock_fd_iocb) and its associated pool. Implement quic_get_dgram_dcid() to retrieve the datagram DCID which must be the same for all the packets in the datagram. Modify quic_lstnr_dgram_read() called by the sock I/O handler to allocate a quic_dgram each time a correct datagram is found and add it to the sock I/O handler rxbuf dgram list.
