Date: Wed, 25 Sep 2019 07:04:00 -0000 [thread overview] Message-ID: <20190925070401.110255.qmail@sourceware.org> (raw) https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;h=7e9b1550fd1c9690bc560404388ba4907d10996a commit 7e9b1550fd1c9690bc560404388ba4907d10996a Author: kib <kib@FreeBSD.org> Date: Tue Sep 17 18:49:13 2019 +0000 Add SIOCGIFDOWNREASON. The ioctl(2) is intended to provide more details about the cause of the down for the link. Eventually we might define a comprehensive list of codes for the situations. But interface also allows the driver to provide free-form null-terminated ASCII string to provide arbitrary non-formalized information. Sample implementation exists for mlx5(4), where the string is fetched from firmware controlling the port.
