From b8210a9e4bea6354eccc5d8a50ecc21ea7486dc9 Mon Sep 17 00:00:00 2001 From: Miroslav Lichvar Date: Fri, 19 May 2017 17:52:35 +0200 Subject: [PATCH] net: define receive timestamp filter for NTP Add HWTSTAMP_FILTER_NTP_ALL to the hwtstamp_rx_filters enum for timestamping of NTP packets. There is currently only one driver (phyter) that could support it directly. CC: Richard Cochran CC: Willem de Bruijn Signed-off-by: Miroslav Lichvar Signed-off-by: David S.
