The branch main has been updated by zec: URL: https://cgit.FreeBSD.org/src/commit/?id=03ef737c544d3dd90a0000c18382db99ccf2ee9a commit 03ef737c544d3dd90a0000c18382db99ccf2ee9a Author: Marko Zec <zec@FreeBSD.org> AuthorDate: 2023-09-23 08:56:56 +0000 Commit: Marko Zec <zec@FreeBSD.org> CommitDate: 2023-09-23 08:56:56 +0000 ng_eiface: switch VNETs when injecting mbufs into netgraph A ng_eiface instance may be on lease to a different vnet while remaining tied to its parent vnet. In such circumstances, before injecting mbufs into netgraph, curvnet must be set to that of the ng_eiface's netgraph node. Mark the vnet transition as QUIET, since otherwise it would be recorded as a curvnet recursion when ng_eiface's ifnet resides in the same (parent) vnet as its netgraph node.
