The branch main has been updated by jhibbits: URL: https://cgit.FreeBSD.org/src/commit/?id=db55051729066a8b162fe2f05e0e2b6c29907e8b commit db55051729066a8b162fe2f05e0e2b6c29907e8b Author: Justin Hibbits <jhibbits@FreeBSD.org> AuthorDate: 2023-08-25 15:36:35 +0000 Commit: Justin Hibbits <jhibbits@FreeBSD.org> CommitDate: 2023-08-26 14:32:12 +0000 dtsec: Support multicast receive. Implemented based on the tsec(4) multicast support. This is the minimum required to support VLANs. The hardware does support vlan tagging, among other acceleration features, which will be added at a later time.
