The branch main has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=acbc176c3dfdfebd047507dc7d843f8cc10984a8 commit acbc176c3dfdfebd047507dc7d843f8cc10984a8 Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2024-03-23 00:25:07 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2024-03-23 00:25:07 +0000 nvmecontrol: Display additional Fabrics-related fields for cdata Some of these fields are specific to Fabrics controllers (such as the size of capsules) while other fields are shared with PCI-e controllers, but are more relevant for Fabrics controllers (such as KeepAlive timer properties).
