Merge branch 'siocghwtstamp' of git://git.kernel.org/pub/scm/linux/kernel/git/bwh/sfc-next
Ben Hutchings says: ==================== SIOCGHWTSTAMP ioctl 1. Add the SIOCGHWTSTAMP ioctl and update the timestamping documentation. 2. Implement SIOCGHWTSTAMP in most drivers that support SIOCSHWTSTAMP. 3. Add a test program to exercise SIOC{G,S}HWTSTAMP. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
