The branch main has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=9040277864ab28cabfc53f238e900bc19ac75d7e commit 9040277864ab28cabfc53f238e900bc19ac75d7e Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2025-11-19 02:13:15 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2025-11-19 02:25:38 +0000 iwlwifi/mld: only get tid after checking that it is a dataqos frame Like we did for mvm, only get the tid after all the other checks are done by the function in order to not trigger an assert. Linux will likely return a random value there which later is not used as the driver does an early return. In LinuxKPI we do check that the frame assumptions hold up, which does not go so well for a random frame.
