Subject: [PATCH v1 net-next 0/3] ECN offload handling for AccECN series

From: Chia-Yu Chang <chia-yu.chang@...ia-bell-labs.com>

Hello,

Please find the v2 ECN offload handling for AccECN patch series. It aims
to avoid potential CWR flag corruption due to RFC3168 ECN offload, because
this flag is part of ACE signal used for Accurate ECN protocol (RFC9768).

Best regards,
Chia-Yu

v2:
- Replace VIRTIO_NET_HDR_GSO_ECN with VIRTIO_NET_HDR_GSO_ECN_FLAGS
