The branch main has been updated by jhibbits: URL: https://cgit.FreeBSD.org/src/commit/?id=f766d1d5a7c65d001c443e3fd21694645d58b8b2 commit f766d1d5a7c65d001c443e3fd21694645d58b8b2 Author: Justin Hibbits <jhibbits@FreeBSD.org> AuthorDate: 2023-04-10 18:20:00 +0000 Commit: Justin Hibbits <jhibbits@FreeBSD.org> CommitDate: 2023-05-02 18:34:47 +0000 IfAPI: Add if_maddr_empty() to check for any maddrs if_llmaddr_count() only counts link-level multicast addresses. hv_netvsc(4) needs to know if there are any multicast addresses. Since hv_netvsc(4) is the only instance where this would be used, make it a simple boolean. If others need a if_maddr_count(), that can be added in the future.
