From fd468c74bd4d6949736810a80d6ca05eb20fba84 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Thu, 14 Nov 2013 01:19:29 +0000 Subject: net_tstamp: Add SIOCGHWTSTAMP ioctl to match SIOCSHWTSTAMP SIOCSHWTSTAMP returns the real configuration to the application using it, but there is currently no way for any other application to find out the configuration non-destructively. Add a new ioctl for this, making it unprivileged.
