The branch stable/12 has been updated by kbowling (ports committer): URL: https://cgit.FreeBSD.org/src/commit/?id=cfb3a1dee11c776a6aedd1c8fb3f86f9b7240e9a commit cfb3a1dee11c776a6aedd1c8fb3f86f9b7240e9a Author: Eric Joyner <erj@FreeBSD.org> AuthorDate: 2019-07-23 18:14:32 +0000 Commit: Kevin Bowling <kbowling@FreeBSD.org> CommitDate: 2021-10-03 01:53:12 +0000 ixgbe(4): Fix enabling/disabling and reconfiguration of queues - Wrong order of casting and bit shift caused that enabling and disabling queues didn't work properly for queues number larger than 32. Use literals with right suffix instead. - TX ring tail address was not updated during reinitiailzation of TX structures. It could block sending traffic. - Also remove unused variables 'eims' and 'active_queues'.
