The branch main has been updated by jhibbits: URL: https://cgit.FreeBSD.org/src/commit/?id=189c3729d84f620a6be10f62daef32ae9a47eff3 commit 189c3729d84f620a6be10f62daef32ae9a47eff3 Author: Justin Hibbits <jhibbits@FreeBSD.org> AuthorDate: 2023-02-10 15:53:19 +0000 Commit: Justin Hibbits <jhibbits@FreeBSD.org> CommitDate: 2023-02-14 15:21:19 +0000 IfAPI: More accessors Summary: Add the following accessors needed by infiniband drivers: * if_getaddrlen() * if_setbroadcastaddr() * if_resolvemulti() With these accessors, and additional changes on the drivers' side, an amd64 kernel can be compiled with `struct ifnet` completely hidden.
