The branch main has been updated by kbowling: URL: https://cgit.FreeBSD.org/src/commit/?id=786c71845f80b8bf733d07f9155de9740a8cbc19 commit 786c71845f80b8bf733d07f9155de9740a8cbc19 Author: Wei Zhao <wei.zhao1@intel.com> AuthorDate: 2026-07-28 11:20:32 +0000 Commit: Kevin Bowling <kbowling@FreeBSD.org> CommitDate: 2026-07-31 11:38:25 +0000 ixgbe: disable VF multicast reception for empty list Clear ROMPE for an empty list and enable it only for a nonempty list. FreeBSD already clears ROMPE when resetting a VF, so that part of the DPDK change is not needed. DPDK commit message net/ixgbe: fix over using multicast table for VF VMOLR.ROMPE allows a VF to receive packets matching the shared multicast table. Leaving it enabled after the VF removes its last multicast address lets PF or peer-VF table entries continue selecting that VF.
