QUIC: ngx_quic_bpf module. The quic kernel bpf helper inspects packet payload for DCID, extracts key and routes the packet into socket matching the key. Due to reuseport feature, each worker owns a personal socket, which is identified by the same key, used to create DCID. BPF objects are locked in RAM and are subject to RLIMIT_MEMLOCK. The "ulimit -l" command may be used to setup proper limits, if maps cannot be created with EPERM or updated with ETOOLONG.
