The branch stable/15 has been updated by tuexen: URL: https://cgit.FreeBSD.org/src/commit/?id=28f2d9b86de5aa337f9f5f28e95e112722cfa14d commit 28f2d9b86de5aa337f9f5f28e95e112722cfa14d Author: Timo Völker <timo.voelker@fh-muenster.de> AuthorDate: 2025-09-16 21:37:45 +0000 Commit: Michael Tuexen <tuexen@FreeBSD.org> CommitDate: 2025-09-17 04:49:54 +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.
