The branch main has been updated by dab: URL: https://cgit.FreeBSD.org/src/commit/?id=2f176a2b20107f7a9132242223e9eef657400514 commit 2f176a2b20107f7a9132242223e9eef657400514 Author: David Bright <dab@FreeBSD.org> AuthorDate: 2021-05-24 19:02:43 +0000 Commit: David Bright <dab@FreeBSD.org> CommitDate: 2021-06-01 15:55:44 +0000 pciconf: Fix up pciconf -lc output The pciconf command fails to emit newlines when particular ecap field values are seen. Fix them up. This has been seen on several systems at $JOB. The documentation for PCI capabilities says that capability type 0 should not be used once the spec for PCI capabilities was published, but that seems more wishful-thinking than reality. pciconf also chooses not to print fields related to field values that are zero, but it seems several of these fields are zero on actual hardware.
