The branch stable/14 has been updated by tuexen: URL: https://cgit.FreeBSD.org/src/commit/?id=a16c7286b5c4c63867626fa9fcfba82d8edec4ba commit a16c7286b5c4c63867626fa9fcfba82d8edec4ba Author: Timo Völker <timo.voelker@fh-muenster.de> AuthorDate: 2025-09-16 21:37:45 +0000 Commit: Michael Tuexen <tuexen@FreeBSD.org> CommitDate: 2025-09-22 19:31:17 +0000 vtnet: deprecate loader tunable fixup_needs_csum If this tunable is enabled and vtnet receives a packet with VIRTIO_NET_HDR_F_NEEDS_CSUM set, vtnet computes the TCP/UDP checksum and writes it in the checksum field. This was somewhat useful when vtnet pretended that such a packet has a correct checksum and set the mbuf flag CSUM_DATA_VALID. But this is not the case anymore.
