The branch stable/12 has been updated by kp: URL: https://cgit.FreeBSD.org/src/commit/?id=217e75db75d4646f73b078d898d3ce7366dad77a commit 217e75db75d4646f73b078d898d3ce7366dad77a Author: Luiz Otavio O Souza <loos@FreeBSD.org> AuthorDate: 2021-08-17 07:54:40 +0000 Commit: Kristof Provost <kp@FreeBSD.org> CommitDate: 2021-08-26 07:26:45 +0000 ipfw: use unsigned int for dummynet bandwidth This allows the maximum value of 4294967295 (~4Gb/s) instead of previous value of 2147483647 (~2Gb/s).
