When using s2n-quic-qns with XDP, are there any additional system or network interface (NIC) settings that must be configured? #2870
Description
Problem:
I tried to use s2n-quic XDP as a server to validate XDP QUIC transport. s2n-quic XDP server receives initial packets without problems, but packets it sends are not received by the client.
I used tcpdump to capture packets and captured the server's replies to the client, but the client application process did not receive the packets.
If not using XDP, the client and server can communicate no problem.
s2n-quic-qns server:
./target/release/s2n-quic-qns interop server --port 4433 --www-dir ./ --max-mtu 1500 --application-protocols h3 --xdp-stats --bpf-trace
The recv logs:
The sent logs:
ebpf log in server log(I think the server sent the packet successfully, the ebpf pass the packet to the kernel stack)
tcpdump:
