From eb3babf7b4cf3793e0ed48030db958ace6546d7e Mon Sep 17 00:00:00 2001 From: Laurent Vivier Date: Tue, 24 Feb 2026 13:22:27 +0100 Subject: tcp_vu, udp_vu: Fix comment headers for header length functions The comment headers for tcp_vu_hdrlen() and udp_vu_hdrlen() described the return value as "the size of the header in level 2 frame", but these functions also include the virtio net header, which is not part of the L2 frame.
